Most people won't pay extra for fish that are kept an extra 3+ weeks or so in order for a proper QT, so it's a double edged sword.
And FWIW, I'm a member of the DC Plant club, it's maybe 4-5 hours drive each way (location varied) and pre=covid we went to all the meetings, it was worth it to us to get out of the house and we both work from home anyway.
It's not an all inclusive list, just the best one from the top of my head... posting where you are, at least the state or part of it is helpful.. I maybe know 15 clubs within 6 or so hours of here in eastern PA for example, quite sure not all of them will be on that list because of them not having a large (or any) aquarium plant presence but you can bet that any club with member (unless everyone is strictly SW) will have some sort of plants.
