Cheap but decent bow, 30lbs, even less. 30lb is a lot more holding weight than you'll be used to with wheel bows, so there'll be body work there.
At a club in Paris, very reputable Oly coaches start grown men on 26lb. They are shooting much heavier, very well, within a year.
You should be able to draw and hold with ease, for over a few dozen arrows at least, long and rewarding practice sessions.
It has to be easy while you are learning, or you'll never likely attain good and repeatable form. Thousands of mediocre (at best) archers out there that started shooting heavy. Snap shooting, little to no shot control, within a year. Just so common it's almost banal mentioning it.
Then once you are grouping well, walk up 5lb to 35lb. For this an inexpensive takedown or ILF makes a lot of sense. You just buy new limbs for it as you go.
A long and very rewarding journey. Short of getting a coach, it cannot be rushed
