The best site for a newbie is PokerStars or Americas Cardroom, imo. The reason is because of the variety of games they have. The buy-ins range anywhere from $0 to $1,000+. 🤑
Hold 'em is prolly the most popular game but PLO and PLO8 have a strong congregation of returning players. They even have some stud games at ACR. I think at PS's as well.
As far as bot risks I wouldn't worry too much about it. They can be beaten and all money is good money, as far as I'm concerned.
