haven't really found a need or desire to upgrade beyond maxing the ram and shoving an ssd in it.
One time, I bought a fancy wallet made of stainless steel (threads, woven into thin sheets, backed by plastic). For MONTHS, I was paranoid about leaving any scratches or blemishes on such a pristine, shiny thing.
Years later, it's still my wallet, and has enough blemishes and scratches for me to not care as much. One new scratch or blemish would be unnoticeable among the others. It still holds itself together just fine, and it still has the 'slippery' in-pocket texture that I like.
Point being, as long as you take decent care of Your Precious, it'll be fine with the exterior wear and tear.
I've also got a $4k-ish ring made with white gold, and it came with a fucking mirror-like polish. Tiny scratches or dings were 'End of the world", until I was able to identify "inside" and "outside" orientation via a small blemish on one side.
I've been using the same briefcase for probably 30 years (bought to hold a laptop yet still fit under an airline seat). It's pretty beat up — but for lawyers a beat-up briefcase is something of a status symbol, kind of like Willie Nelson's guitar "Trigger."

If it's any consolation, the Apple M laptops' keyboards aren't the infamous butterfly ones.
More generally, I don't worry too much about pristine keyboards. I wipe them down every week or two with 91% isopropyl alcohol and tissue paper and they're good as new. They're going to get grimy because you need to touch them, so it's not worth the worry.
As for the screen, I just take a swiffer duster to them anytime I notice dust buildup. If I notice any liquid stains, like the keyboards I just take 91% isopropyl alcohol and tissue paper to them. Good as new.
I never worried about it at all. There's holes in the keyboard and through the laptop to deal with liquid spills. The case was a nice hard plastic with enough flex to prevent breaking.
Honestly, if I dropped it on the floor - I'd check the floor first for any damage.
Taking it apart was straightforward, albeit a bit frustrating. I found the MBP mid-2012 unibodys much, much easier to take apart and clean.
I recently decided to upgrade and bought a M1 MBP Pro off of a college kid wanting to get a gaming laptop. It's a huge upgrade and I actually find myself loving MacOS. Everything feels so nice and looks so nice.
But now I am just terrified for this laptop. It has a hard case. I'm meticulous about a clean keyboard and screen (fingerprint magnet). I keep any and all liquids very, very far away. I never place it anywhere where there may be dust.
I sometimes wonder if the stress is worth it. I'm tempted to buy myself an X220 or something else in the X series since the T530 was heavy to lug around.
