Resurrect my Mi Note 3

[caceresvd]

I have this phone for almost 4 years now and recently I got a Mi 11 Pro that is my main phone. I wanna give this one a second life by restarting it from 0, as I got a lot of problems on the last year; sudden drop of battery, the up volume button not working (even if on the twrp screen is working), and slowlinness in general, as its full of documents, pics, etc.
I wanted to know whats the safest way to do this, as I'll back up all the documents but i want the system and everything to start from 0 so (hopefully) some of the problems are solved. Im currently running on xiaomi.eu 20.6.18 Beta (miui 12.1), as far as I know the last weekly release?
I guess I should get the last stable rom (xiaomi.eu_multi_MINote3_V12.0.1.0.PCHCNXM_v12-9. ??) and install it through TWRP, then wipe cache, dalvik, data, and something else?
I wanna do the installation as clean as possible...
Thanks for the help!!

Wipe system? Why?...

Wipe system? Why?...

I know it's not recommended on newer phones with dynamic partitions but Mi Note 3 is old and it never gave me problems wiping System.

Thanks! Do i do it in that order, so flashing the rom the last thing? After the rom is flashed, I reboot system directly?
