I think the MacBook charge controller (probably not all model years) will reduce the max charge to below 100% if it detects prolonged AC use to reduce wear. Of course, this means you won't actually get 100% when you may need it for the first deeper discharge.
One nice thing about the Dell XPS laptops (others too I assume) is that you can configure min/max charge in the BIOS.
In any case, just leaving my devices plugged in most of the time seems to have the battery last many years, with the exception of some Android phones that don't tolerate this at all. Improvements in the last 5-10 years have probably come from better charge controllers.
