Multi Sport Collection

I will start out with saying I have never gone about trying to sell my cards but collecting was a big hobby of mine for a long time.

The vast majority of my collection is baseball, football, basketball in that order. Small amount of other things such as soccer, golf, wwe, nascar, hockey, etc.

Tried to start cataloguing everything with the Collx app. I know the true value shown on that is necessarily correct, I just needed somewhere to start. Roughly 3.8k is what I have uploaded (1,960 cards) on top of that I also have three storage bins full of bulk, unopened wax packs, full sets between 1980-1993 baseball, thousands of low value singles, unopened nfl packs from Mexico, 1990 soccer packs, hockey packs, just for starters.

I would much prefer to sell everything in one clean transaction than taking the time piecing it out. Obviously I’m not looking for full value of everything, I would be willing to make a good deal just to not do the leg work. Where should I go to sell?

Thanks you to anyone that gives advice!
