Surfing quest - help the struggling fellow.. :)

Hello everyone,
Another beginner here moaning about impossible quest of surfing
)
I am 83kg (182 lbs) and 186cm tall (6.1 foot), 30 yo. I used to be very active(long distance triathlons) but had a 3 year break and office work in UK which made me loose all the fitness I ever had
That's why I moved out of there..
After surfing for ~2 weeks in whitewater, I have upgraded from 9 foot softboard to a 7.6 foot hardboard - I wanted to have my own rather than keep renting. Of course the difference was massive and it was like starting from day one. I couldn't even stay stable while paddling... the difference in float, length/width looked massive to me.. now it's getting slowly better..
I am trying to be in the water almost every day (I live on the beach), but of course conditions are not always perfect. So my current "surfing level" is ~3-4 weeks in the water.. That's the reason I came here for help - I know "practice practice practice" mantra but I just believe that small advice goes long way .. and I had enough playtime to justify some questions..
My current problems so far in the whitewater (I try to stick to white stuff so far..)
1. Separation from the board
Sometimes I get separated from the board, and the board get's launched ahead of me. My possible guesses.. a) more wax? b) too slow compared to wave speed? c) unconsciously lift my legs and water get's in between myself and the board? d) too close to breaking waves, and the whitewater is still very violent?
2. Sloppy pop-up and fall
At home, on the floor, or on the sand, my pop-up looks perfect to me.. feet landing in the correct position, timing etc... but something changes in water. Is it instability, lack of balance/coordination.. 7 times out of 10 semi-successful pop-ups my feet land close together and to far behind on the board, which means I have to adjust my footing straight away or fall. To adjust it, I have to look down the board, which causes another reason to fall down..
When you pop-up, do you shift the board backwards a bit, to reposition it better, or is it just a matter of throwing your front leg more forward.. ?
Or maybe I'm just too tired from daily surf and exercising at home, and my body wants rest..
I think surfing seems so challenging to me because I never was flexible or had good balance..
Did those balance boards made any difference for any of you? I am considering them, but I don't want to start buying "gadgets" where other solutions could be applied.. I had enough of hobbies where you would keep buying stuff.. And this is what I like so much about surfing. Board, wetsuit and me. simple.
