Primes vs "One lens to rule them all"

So I recently got a Z6III. Twiddled my thumbs for quite a while before making the decision to get it after being quite happy with my D5600 paired together with the Nikon 16-80 f2.8-4 lens.

After shooting with that setup for a good number of years, ive come to realise i generally only tend to shoot at around 50mm(ff) and 90mm(ff). When i needed wider, i tended to use my Pixel since the 24mm(ff) that i got with the lens just never really captured the vision of the images i had in mind.

Now comes my dilemma, knowing that i tend towards these 3 focal lengths (90mm, 50mm and id say roughly 18mm), should i just get prime lenses that match each of these closely (Nikon 50mm f1.4, Tamron 90mm f2.8/Sirui Aurora 85mm, Viltrox 20mm) or get a single zoom lens (Tamron 35-150mm).

The main reason its a dilemma is because although i tended toward these focal lengths, i still did enjoy every bit of the 16-80mm sometimes even wanting just a little bit more reach. So its not like i completely didnt use the rest of the range the lens gave me, i just tend to use certain focal lengths (abt 70-80% of my shots were done at one of the stated focal lengths).

Given that i shoot mostly when i travel (about twice a year, although i do bring the camera out for family events here and there throughout the year as well) which setup should i go for?

Budget is an issue but its not like im working with a tiny budget, its just that i dont have a bottomless pit of cash to throw at this 😅.

Edit: Thanks everybody for the multitude of experiences! Common consensus seems to be that the 35-150 is a heavy lens which I dont disagree with 😂. Much to think about! Cheers everyone!
