The Golf Club is, in my opinion, hands down the best PC golf game there is! You can play by yourself, against friends, against random opponents, in leagues, tournaments, skins games, just about anything you can think of. And it can be bought dirt cheap through 3rd party key resellers, like on this website: https://www.kinguin.net/category/21642/the-golf-club-collector-s-edition-bundle-steam-cd-key/. Here's some in-game footage:
They also just released The Golf Club 2 in June, but since it's so new you can pretty much only get it at full price ($40). The videos of it look pretty sweet though!
