I use the Alpha 6000, the Alpha 6500 new and the Alpha 7M2 and will soon buy the Alpha 7M3 and have various lenses including many fixed focal lengths as they are sharper. I think what you need and what I would recommend would be a 24-70 mm this focal length is a reporter focal length so to speak and covers pretty much everything from wide angle, to portrait etc. Suggestion here:
Sony FE 24-70mm f/4 ZA OSS Zeiss good price 899.- at the moment, was over 1000.- a few months ago.
Think for your super camera you must also have a good lens, would be a shame if you buy a sh.... lens that can't reproduce the quality of the camera.
Nevertheless, here is something cheaper:
A 24-240mm that covers a lot and is approx. 860.- not quite as sharp as the upper Zeiss but for private photography and a start certainly a good choice, for myself in the professional field rather not, but still not bad and with the price you are still there.

Then here's one that I use myself - the 55mm 1.8 for about 850 - a real gem, very good but not a telephoto zoom.
I think one of the first two is better for you, the first one is sharper and has better quality and the second one covers a wider range with 24-240.
As I said, I like to shoot with fixed focal lengths because they are just a little better in quality, but they are also more expensive.
So I can only advise you to spend a little more, in your case I would choose the first one, unless you also want to photograph things that are further away, i.e. zoom in on animals etc. then the second one would be the first choice.
Hope this was of help to you.
