Which program for switching between windows in macOS is suitable for the conditions?

Question

macOS

Hello.
The question is simple, I work mainly in 4 windows (browser, Postman, Sequel Pro, Sublime text), I need to switch between them, but here's the moment - just through CMD + Tab we effectively switch between the last two windows, if you need to switch to another - then you have to click (or I don't know something). I don't like working in full screen mode with desktops.
Is there a program that allows you to set a specific window for each program, assign it to a number, and when you click on some CMD + Shift + 1,2,3,4, it will switch the window to the desired one? ..
Thank you for your time.
