Since you have a very low cycle count battery, I understand that you’d want to preserve it. However, due to your trackpad issues, I’d recommend a full upper case assembly anyways as removing the battery is a very tedious and unpleasant job and doesn’t require more steps. But, since you'd plan on replacing the battery anyways, I’d just do a trackpad replacement. You can find used ones on eBay for around $30 depending on where you are and you just need a plastic syringe and a bottle of acetone. Use a plastic card that you don’t need like an old gift card and try to open up some space. Just add a few drops, not a lot as you might risk damaging the cells. You can always add more so be very careful. Patience is very important for this job. But it can be done and it’s not very expensive to do it yourself.

Is the heat sink screwed on tight? I’d recommend reinstalling thermal paste on the CPU and dusting off the vents and fans

70% alcohol is fine. I’ve used it for building/rebuilding many desktops and my CPU’s have been really cool. I also use nail polish remover wipes because they’re lint-free and clean really well Here’s a similar one to the one I have

Have you tried using ReiBoot? Also, a DFU mode -> iTunes restore as a new iPhone (not restoring from a backup) is a sure fire way to fix problems.
