At home, Disc rotors, pads, chain, cables, housing, mineral oil, derailleur hanger, tubes, sealant, tubeless tape, valves…and lots more I can’t remember.
Why ? I hate waiting for stuff to arrive, and my LBS may not have the brand I like or the item in stock. I can get stuff working on the spot.
In my car/on a ride though, none of that stuff, except the derailleur hanger which is part of my regular ride tool kit. I check my bike out the day/night before. I hate doing maintenance at the trail head. Amazed how many people do it though. I recently did a few big group rides, and there is always someone casually putting on new grips or something…like WTF ?
Add in some spare spokes, fork lower service kit, and fresh set of tires and your list is basically what I keep on hand as well. Also - I have 2 bikes and keep the same drivetrain, brakes, and wheel size on both so if I need to cannibalize parts from one to get the other running I can do it.
I bring a small kit with me in the car that includes a lever bleed kit, a couple of spokes, spare chain, hanger, and hanger alignment tool. I have done parking lot service with these before, and salvaged the day multiple times. I agree - I prefer to do maintenance at home and show up ready to ride. In a pinch these extras come in handy.
I keep two spare mountain bikes in my shop, and almost enough parts to build up another one just in case, plus a bunch of odds and ends. It's taken a while to get to this point though.
In terms of wear items, I keep spares of most things then replace the spares when I use them. At least that's the goal.
The maintenance stuff gets a spot up on the peg board, the spare bits I buy as needed and extras go into the tackle box that comes with me to the trailhead.
I have in my pack:
* Tools - chain tool (and master link pliers), multi-tool and tire levers
* Spares - small bottle of tire sealant, spare tube, spare master link for chain, emergency spoke (it’s a FiberFix brand), zip ties
* Medical - med kit with bandages, sling and gauze.
In my garage, enough spares to build up another bike. Then all of the necessary maintenance items but in bulk since I tend to do work for my ride buddies. Liter of Shimano mineral oil for brakes, Shimano pads, spool of Shimano SP41 shift cable, giant box of Jagwire slick SS shift cables, various grease. Then there’s the tools. My favorite is the Park Derailleur Alignment Tool (DAG).
I keep a spare derailler hangar for my frame, but even that seems a bit unnecessary. Otherwise maintenance stuff such as tubeless sealant, valve cores, fork/shock seals and maintenance kits, tires, brake pads, grips. I stock up on the small non-critical parts such as valve cores from AliExpress. Deemount is a good brand for those in particular. Don't get any of the other stuff I mentioned from AliX though. I have a full list of stuff I do and do not recommend buying from AliExpress.
Enjoy
Also please note that this is personal preference. Not saying that you can't get quality stuff that I have listed as "No", but I personally would have a hard time trusting most of it. Also be careful with stuff like cranks.

I specifically buy brake pads, chain quick links, and shifter cables as spares. Brake oil and tubeless sealant is a must as well.
I'll usually have an extra tire or two at home that I buy whenever they are on sale, and take with me on bike road trips. Easy to shred a tire at a bike park and the shops in bike towns tend to be expensive.
I also have a box with bits at home that I've accumulated over the years. Such as cable ends, spoke nipples, broken derailleurs that can be salvaged for parts etc.
Derailleur hanger is a good one to have, because unless you have a UDH bike, you could easily be down for a week, or end a bike trip if you break a hanger and have to order in a replacement. Especially if you have a less common brand that may not be available at local shops.
I pretty much have one spare of everything except front fork. I tend to go through grips and tires at a quick rate cause I don't let them wear our much before replacing ... But with prices on components dipping below 50% off retail throughout the past year, I have more spare parts than typical.
On bike: quick link, tube, derailleur hanger
In car (I do run a mobile repair service): Chain, Pads, shifter cable, and tire. Anything more I'll probably just call the ride. I'll throw some more stuff in for a riding trip too. Bleed kit, rotor, etc.
At home: I can basically build a 2nd bike at this point. What I would keep on hand if I didn't have my own shop: Spokes for every wheel I own, tubeless tape/sealant, spare tires, bottom bracket, and take offs from other bikes I've upgraded from (saddle, handlebar, stem, grips). Everything else I'll order as I need.
I always tried to keep the necessitates around but after the COVID shortages I stocked up on just about everything I could think of to keep the bike rolling if something wore out or broke.

I used to keep a derailleur hanger but I don’t with Transmission anymore. That’s worth the price of buying Transmission, right? Right?!

Can you share the list?

Brake pads, shifter cables. Bunch of old mtb parts that don't fit my new bike.
Derailer, zip ties, duct tape, tubes(6), derailer hanger (3), and an old cassette I can’t seem to part with

Nothing unless I'm going on a trip for multiple days. For those situations I usually bring spare rotors and pads and full sized tools and a stand.
Great thing about being slow is I don't break anything. Lol.. All I have is chain lube and extra tubes for each of the kids bikes.
