What wheel size? Without knowing that (and where you generally ride) there’s not much point recommending particular setups.
If you are going towards a 1x system then on a 29er either 30T or 32T chainring, add two teeth for 650B and another two for 26″. Out back, any of the wide range cassettes will do, the Sunrace ones are fine. I don’t know about the really wide range cassettes but with a 1×10 setup I lose about 3 gear ratios when compared with my previous 3×9 setup, I’ve chosen gearing that loses one at the bottom end and two at the top.
On my 29er I started with 30T, struggled a bit to begin with, especially on some steeper hills. After a couple of months I’d got stronger and when I came to replace the chainring I went to 32T (actually it was because the shop didn’t have a 30T in stock and I needed a new one there and then).
Most of your riding should be using the middle of your gear range (regardless of whether it’s 1x, 2x or 3x). I’m very rarely in either the top or bottom gear, by rarely I mean a few minutes per month.
