Yes, both are lossy formats, so transcoding introduces a small amount of additional quality loss. Using 320 kbps MP3 minimizes this effect.
No. DRM-protected M4A files from Apple Music cannot be converted. Only DRM-free M4A files (such as purchases or recordings) are supported.
MP3 has near-universal device and software support. While M4A (AAC) is technically more efficient, MP3 is the safest choice for maximum compatibility.
