have there been any recent updates to this question: Which dual screen extender can be used with an M3 chip Macbook Air without having to be in clamshell mode? And what would be the names, locations (websites) and general price ranges? Thanks!
MacBook Air 15″, macOS 26.6
The MacBook Air M3 (13" or 15") supports only one additional display in non-clamshell mode up to 6K resolution at 60Hz, or two screens in clamshell mode, the 2nd display up to 5K resolution at 60Hz.

You will find plenty of manufacturers offering such displays. You have to weight in your budget, your usage (photography...) with the performance of the display. 4K display are less expensive than 5K; 5K less than 6K.
If you are interested in Apple hardware, Apple sells their own displays:
