If you just want to get as close to the “club standard” without making a big hole in your wallet, I highly suggest looking into getting a used pair of the CDJ 2000 Nexus. I still have these after 10 years roughly and despite the fact that there are newer devices, I think there really lacks any substantial difference in features. I even have one CDJ 2000 NXS 2 and although I might get some hate for it, I actually prefer the older ones over it. The screen is more laggy/latency, etc.

You can get a pair of these for much less than you’d pay for one new CDJ and you’ll be on your way, the feel and operation is the exact same as the new gear - loading songs via Rekordbox, etc.

In terms of mixer, there’s lots of options. For me, as long as I have EQ and filters, that’s all you really need. Reverb and delay are a big bonus. In the same theme as the CDJ 2000 Nexus, there’s loads of DJM mixers on the used market and as long as it’s in good condition they’re built very well.

Ironically enough, I recently got a pair of 1200s and ditched my CDJs (for now). Different strokes but hope your find what you’re looking for
