Are you still on stock Android, or have you updated to LineageOS?
I recall the problem with Chrome refreshing the page from the fingerprint sensor was present in the stock Android, but fixed in LOS.
IIRC, the work around was to switch to Firefox, if you don't switch to LOS.
Some of your other issues might work better with LOS, too.
No real downside to it, except for the time it takes to set it up.
