I work in brightly lit environments frequently. My personal Mac is an M4 Pro MacBook Pro with the nano-texture display. But my work Mac is an M1 Pro MBP with the regular display (nano-texture wasn't an option), and I don't find the glare to be bad.
Macs notebook computers have gone back and forth between matte/anti-glare and glossy screens. The current crop of Macs, with the exception of the optional nano-texture screen available on M4 MacBook Pros, are all glossy. The advantage of glossy screens is increased contrast, at the expense of propensity for glare. You can see the difference easily with a light source reflected from an old matte PowerBook G4 and a more recent Mac.

The glossier the screen, the greater the apparent contrast. It was a choice on Apple's part, other manufacturers make different choices (and as stated, Apple now offers an option, but not for the MacBook Air).
