I went through this earlier this year after having drivetrain troubles with a 2020 F150.  Here's my thoughts in no particular order -
Toyota's track record of bulletproof-ness seems to be wavering.  If I remember right they recalled almost 100k twin turbo motors from 22-23 models because of potential debris left inside the motors during manufacturing.  Plenty of people on the forums were unhappy with things like parts availability and other issues too.  Like someone above said, the sight lines when I test drove one left a lot to be desired - it felt like I had my collar zipped up tight and ball cap pulled down low over my eyes trying to look out of the truck.  It also felt like the sides of the cab tipped inward more than the other trucks and the interior felt cramped to me but I'm a lanky 6'1" so your mileage may vary.   But bottom line, the new Tundra is very different than the previous generations, someone having 400K miles on a 2002 Tundra is worthless info to apply to a 2026.  And there is a large transmission hump under the back seat of the truck, which was a deal breaker for me.  We put kennels and coolers back there on road trips, and coming from a Ford with a perfectly flat rear floor this was not going to work for us.
GM trucks were... fine.  Didn't love anything, didn't really hate anything.  Still had a hump in the back floor but was smaller than the Toyota.  Inventory on leftover '24s was non-existent back in April so I didn't spend too much time here.
Rams I looked long and hard at and they were a close 2nd.  Some features I liked like the in-floor storage.  Others I didn't like how they require a monthly subscription for features Ford give you for free, like the remote start app on your phone.  I have a few buddies with newer Rams and they love them.  Seems like a lot of the issues from a decade ago like the bodies rusting out and the transmissions blowing up have been addressed.
Ultimately I went with another Ford with the turbo V6.  That motor has been out since 2010 so the issues and maintenance points are known by now (IMO).  To me, Ford's back seat on the crew cab is the best in terms of space and leg room.  Ford also redesigned the drivetrain system I had issues with on my 2020.  I also got the fancy extended warranty.  It was something like 3200 bucks and the dealership said that if something like the tail light (or maybe head light, don't exactly remember) burned out, it's no longer just replacing a bulb.  They're fancy LED contraptions now and the whole thing gets replaced to the tune of $1600.
Ford has the 5.0 V8 and the Ram sales rep told me that next year Ram was looking at bringing back the Hemi.  So those could be options if you don't want a turbo.  I'd have trouble trusting a GM V8 right now after the pushrod debacle in the 6.2.  I suppose their 5.3 V8 has been around forever though.
Baby diesels weren't for me.  Have had enough DEF issues with trucks at work and didn't want that in my personal vehicle.
Ford's bodies are all aluminum now.  Not sure on GM or Toyota but they might be too.  Ram just has aluminum hoods and tailgates I believe.  Regardless I got the underbody and frame coated with whatever it is they spray on them now.
As you've mentioned, way more bells and whistles to go wrong on the new trucks.  Lane assist, steering wheel monitoring, so on and so forth.  Replace the windshield?  Was quoted an extra $400 to recalibrate the forward facing camera that's behind the rear view mirror.  Repaint the driver's door to fix parking lot dings ?  Need to recalibrate the 360 degree cameras on the side mirrors so it works properly.
But other than buying something used I didn't see a way around the "progress and advancements" of technology.  Is what it is, gotta pay to play.
