unfortunately, after re-installing CF and changed it back to Proactive profile, performed CS's config., a scan for unrecognized files -> rebooted -> nothing has changed. CF is still constantly writing ~200-250KB/s

not sure if there is any conflict with avast or just because I'm using HDD, not SSD
I have HD and no problem at all.

Try to examine the process using those:

ProcessActivityView - Show file activity summary in the selected process

ProcessThreadsView - View process threads information On Windows

You can also check in Disk tab, if any file is being accessed at a higher rate, when idle.

You are not going to notice any slowdown from that and i am surprised that you use avast and notice CF. Last time i checked avast, few years ago, it had the worse dirk write in the history and it was in the MB range and not KB.
Avast/AVG is very quiet at idle. I had the same result as on the screenshot, Avast is running at 32-48 B/s, not even close to KB/s.

Task manager only.
task manager and resource monitor are pretty useless to monitor disk activity for single process
I can barely spot any increase in disk usage because the value reported in task manager and resource monitor

process explorer and process hacker are more accurate

It's really quiet for me but regardless 350KB/s is nothing even for an hdd. You are not going to notice any slowdown from that and i am surprised that you use avast and notice CF. Last time i checked avast, few years ago, it had the worse dirk write in the history and it was in the MB range and not KB.
350KB/s is a lot in long term because none of my programs is constantly using more than 1KB/s. Also when I execute something, CF kicks in with >1MB/s
avast has improved a lot recently and also I used my tweaks which significantly reduces disk and CPU usage, and telemetry although it doesn't feel as light as comodo in some tasks
avast was heavy a few years ago

I was trying to read somewhere about read/write and other delta byte
I think the only values we should care are I/O Delta Read Byte and I/O Delta Write Byte
because I/O delta other or I/O total delta also count network and other activity which are not read/written to the disk

CF may not read/write too much to the disk

All of that drive IO would totally wipe out the lifespan of an NVME/m.2 but even worse, it would cause a pretty fast degradation of NVME speed.
I doubt it since most NVMe can last over 100TB of writes in their lifetime with spare flash media.

Hello all. Just in case you are still facing the same strange behavior of excessive disk (HDD/SDD) usage by Comodo Firewall (CIS), try to change logging to the Windows log instead of local database (or disable logging at all for testing). You can do that in the Settings (Advanced Settings): General Settings -> Logging:
