I currently use the Dell S3225QC with my MacBook Air M3, connected via DisplayPort. The image quality is superb. Everything works smoothly, including 4k resolution at 120 Hertz. Only HDR isn‘t available at 4k 120 Hz, only at 4k 60 Hz, which is a bit of a bummer. Is that a known M3 Air limitation? Using different TB or DisplayPort cables makes no difference, connecting the display directly to the MacBook doesn’t help either.
