I don't see any reason to go for anything above 50 large chainring. 52-11. How often is that used at beginner level. My winter and commuting bike runs 48-34. 10-29 cassette. This is ample. Welcome btw.
This is very true. I doubt a beginner could push 50x11 for more than a very few minutes on the flat. The 34 will be in use on even minor hills too. If the OP sticks with it and gets really fit, then other options come in to play.
Personally I'd advise beginners to go with a 48/32 if that was an option.
