My 2c: don't wait with the gym. Start going to the gym 3x a week, start making this a lifetime-habit asap.
Mainly focus on the compound movements: squat, deadlift, bench press etc. The first months you should do them with low weights, practice on learning good form. Try to find someone to give you advice on form. Find a trainer, training buddy, or ask some guys who know what they're doing to advice you. Maybe do some HIIT (on the bike, low joint impact) afterwards. Start very light, gradually build up the intensity.
The other days you should try to walk 30-60 minutes (mainly for overall health, obesity is a killer).
Document your progress (weight, pictures), and try to build good habits (healthy eating/cooking, time-restricted eating, working out) that you can sustain afterwards.
Good luck.
