People will watch lower quality video with good sound for far longer than they will watch good video with bad sound.

I think the cheapest you should go is the Sony EV-10 plus Sigma 16mm 1.4 lens. If those are more than you want to spend, stick with your phone camera because you won't see enough improvement to make it worthwhile.
In either case, watch some YouTube videos about podcast lighting because that will matter more than your camera.
Unless your audience is going to be mainly on a video platform (and even then, the following advice will apply) you should focus your budget on audio equipment, and possibly build a recording booth.
Julie Schiro's videos are a great place to start: https://www.youtube.com/@JulieSchiro
Here are my tiers!
Tier 1: Audio > Video first!
- Get very basic sound treatment done, even just a few panels in front and behind you. ~$100 or cheaper with DIY https://www.youtube.com/watch?v=Q3nS2-HvJMs
- Get a reliable microphone. Samson Q2U is a solid one here if you did step 1.
Tier 2: Improve video
- Improve your lighting. Face a window if you can or get some lamps to balance out lighting. https://www.youtube.com/watch?v=jiUpK0dhWTE
- Use smartphone with app or cable as your virtual webcam. Or if you have $200 get the Logitech Brio
Tier 3: $$$
- Audio: 3x your sound panelling & sound treatment. Put stuff on the ceilings too. If you still have too much money, get Shure MV7 (usb-c which is nice). SM7B honestly isn't needed unless you have a true studio environment with professional sound treatment done.
- Video: Get a Sony a6000 (this is what I use) or a6400 / 6600 and a lens with f1.4 on it. This is what I use: https://www.amazon.com/gp/product/B077BWD2BB/ref=ppx_yo_dt_b...
- Add-ons: Get a dummy battery that plugs into your wall and can run your camera in 'forever power' mode. Get a camera signal -> USB converter like Magewell or Elgato Camlink (what I use): https://www.bhphotovideo.com/c/product/1453840-REG/elgato_sy...
And a good audio recorder will do wonders. Zoom h1n is a quite good budget option. Try searching YouTube for "h1n vs" - there are tons of great options.
The nice thing about this sort of setup is that you can upgrade the lens as needed without having to redo the whole system.
As for lighting, DIY some diffusers for and stick them on some lamps.
I wouldn’t recommend getting into more complicated setups until you’ve tried a recent phone. They’re really quite extraordinary.
I'm giving a talk in a bar next week, and for some reason the organizers are doing audio only recordings, so I'm thinking of setting up a phone to record, but I'll want a 2nd mic as I don't want to have to sync the audio recording from the organizers to my video.
Though I'm not sure if there is a good bluetooth lapel mic. I don't seem to be finding much. I'm wondering if I'll just end up using one of my earbuds, though the audio will probably end up being crap.
Any recommendations?
The most important though is... LIGHTING. I can't stress that enough. Buy a cheap $15 circlear light thingys. That'll improve your image so much!
Mind your settings.
