Keep the kit lens. Depends on our budgets, you can look at 1) Sony 35mm f1.8, 2) Sigma 30mm F1.4 DC DN or 3) Viltrox 33mm f1.4. Personally, I would get the Sigma 30mm f1.4 for the bigger maximum aperture.

camera only for the rich

If you dont mind to use manual focus to try out the focal length / aperture, can go for 7artisans.

Just sharing my pov, im not a professional photographer but a hobbyist who have spent about 10k on it (im using sony a6300).
For kit lens, it really is almost equivalent to what a phone camera can achieve, heck, even samsung s23 ultra zoom is so powerful, or 14pro max ultra wide.

You need a lens that can do something your phone cant achieve. If you want to enjoy landscape, go for ultra wide or telephoto 70-300 (probably the cheapest sony lens for telephoto).
If portrait or night shot? go for sigma 30mm f1.4 or sony 35mm f1.4.
