Should I buy a WQHD monitor?

Question

Monitors

First of all, I would like to understand why there is not a very large selection of monitors with FHD + resolution on the market and why they have such horse prices, unlike phones / tablets, on 5.5 inches of which these same WQHDs manage to be placed ... which prevents proportionally increasing resolution for monitors while maintaining such a high pixel density.
Secondly, in view of the idea of ​​​​purchasing just a WQHD monitor, I would like to ask about the expediency of such an idea as such (whether such monitors have the right to life).
At the moment, I can’t fit on FHD, I don’t want to fence several monitors.
