What is the best solution for my HiFi setup?

I would like to buy a small hi-fi system that I will use for the following:

50% listening to music (via my mobile phone, ideally with bluetooth)
20% listen to music through a turntable
15% as output for my electric piano & my electric guitar (via an audio interface)
15% as speakers for my television

My room is about 18m ^ 2 and my total budget is around 500.- (= 500 euro), which should ideally include an amplifier, if necessary.

After a long search I limited myself to the 3 bookshelf speakers mentioned:

KRK Rokit RP5 G4: 320.- (active)
Klipsch R-51 M: 222.- (passive)
Teufel Ultima 250.- (passive)

Which of these 3 would be best for my needs?

If I'm going to buy a passive speaker, I tend to go for this amplifier:

Sony STR-DH190: 180.-

Would that be a good choice? Or do I need a more expensive or cheaper one for my needs?

If I were to buy an active loudspeaker, would it still be possible to connect it to an amplifier in order to play music on my mobile phone or is this not possible?

And in general: What is the most efficient way to connect my bookshelf speakers to my turntable, audio interface and TV?

The audio interface I use is a Behringer UMC404HD, which until now has been used to connect my instruments and my laptop to small UE booms.

The turntable has not yet been bought either, but I tend towards the Audio-Technica AT-LP120X or the Sony PS-HX500, if this could also have an impact on my HiFi setup (both with preamplifier).

I also considered buying the Teufel Ultima 40 floorstanding loudspeaker instead of shelf boxes, which would stretch the budget a lot. Would it be worth the investment or not in a room my size?

Sorry for the long questionnaire and thank you for all your answers and suggestions!

Only you can find out how the selected devices sound for your taste in a listening comparison.

Loudspeakers are always connected to an amplifier.
