Charge habits with batteries make a huge difference. If your use pattern is that once per day, you take the device from 100% to 10%, you put a lot more wear on the battery than if it kind of hovers in the 30%-80% range for example, or if it just hangs out nearish top-of-charge all day when you're at your desk.
Hot take: people should get used to, and expect to, replace device batteries 1 or 2 times during the device lifetime. They're the main limiting factor on portable device longevity, and engineers make all kinds of design tradeoffs just to make that 1 battery that the device ships with last long enough to not annoy users. If we could get people used to taking their device in for a battery once every couple of years, we could dramatically reduce device waste, and also unlock functionality that's hidden behind battery-preserving mechanisms.
BatFi is a macOS application which will prevent your battery from charging to over 80% by default. macOS does have a version of this built-in but it’s “intelligent charging” I don’t really trust, and I’d rather just have a hard 80% limit except when I override that.

I agree that people should get used to replacing device batteries, but if you accept that then you should just stop worrying about charge habits. An MBP that doesn't have a defective or extreme-heat-damaged battery should stay above 80% battery capacity for at least 600 charge cycles without any special care at all. That's many years of regular charging, and 80% capacity is still good for all day usage.
Agree, and this is in fact how I treat my devices. I can easily do my own battery replacements on laptops, although I still approach phones with suspicion due to the water ingress problem.
