Latest firmware will probably be OK. For a long time I simply used latest firmware, but a while ago I had the 'error 7' issue when updating my ROM. Advice was to downgrade my firmware to the stated version 8.4.19, after that I didn't have any issue updating my ROM. Try it out, if you have errors thrown at you during a LineageOS install, install the recommended firmware. If not, you'll be OK.
I installed the latest, got error 7, had to edit updater script and now camera isnt working and fingerprint fails to enroll.
I think latest miui will not work well, xiaomi added something.
I installed FW 8.8.16 as a test for now, and fingerprints work but not camera, couldn't there be a newer better firmware? as 8.4.19 is kinda old.
