One of the many utilities I love that comes with my Set App subscription is AlDente Pro. As others have pointed out, it allows me to set 80% as the max for my battery and it also will change the color of the LED on the magsafe connector to green once it gets to 80% and charging stops.
I had optimized battery charging enabled but my Mac seemed to always charge to 100% - with Al Dente I can force it to do what I want.
And recently I found Al Dente pausing charging because the battery temp got too warm. So then I went down a rabbit hole and found out I could tweak the fans up slightly higher with iStat Menus (also part of my Set app sub).
There are other utilities that will do similar things - those just happen to be two I use, especially since I tend to use my MBP plugged in the majority of the time.
