New to group and Flashing

Hi, Just came across the videos and tutorials for rooting, installing and flashing. I have a OnePlusOne bacon which is a fairly old phone but I was able to get Android 9p with gapps as per online tutorials. I am going to try and get Android 10 or dare I say 11 on it. Any suggestions or recommendations would be great. I just downloaded Lineage and will see how that works with NikGapps as i read in one thread it should work.

Wish me luck!
