WST, you should be at the experience where you can judge your rate of descent visually looking outside. The only important instrument inside approaching flare is IAS. Ignore everything else and give it a couple glances so you don't get slow.
It has always worked for me and being mechanical on flare using RA and reducing power at a certain altitude isn't good because sometimes you get a wind change very low to the runway and you have to correct for it. Just fly your visual approach touchdown and don't get slow. Make it simple. It always worked for me. Once in a while you get a sinker or a gust so be ready to not let it FU your landing.
I wish I could have flown an airliner with 300 hrs. It took me 5500 hrs. Good luck.
