Installing Lineage by itself will drastically reduce power consumption on many devices, as vendor bloat is wiped. A net gain is possible, even with ACC 80% in place.
With a Pixel, there is less bloat, so it is less of a factor with this particular device. However, you don't get the full suite of Chrome/Maps/Gmail/Drive/Photos/etc. installed by default, and what you have not installed will not drain your battery.
In any case, one would hope that Google's safeguards are equaled by ACC.
This seems surprisingly high to me, unless you're constantly on extreme power saving mode. I liked the 4a and still have it in a drawer, but replaced it partly because I couldn't order a new screen and the battery life was frustratingly terrible after a while
It seems to in my house - possibly the wifi signal is not strong enough where I leave my phone and it is constantly searching. I also find that on wifi data, apps constantly update and sync themselves - they don't do this on metered network data.

Sounds like you should move your AP? There's no way that communicating with an AP tens of feet away is going to require less power than communicating with a tower hundreds of feet away.

You can set wifi connections to "metered" on both android and ios. It doesn't allow you to cut off data entirely (like you can on cellular data), but should have similar effects to being on cellular.
That will reduce future wear, but won't suddenly make the battery better. If anything it'll make the battery even worse, at least in the short term.
