FLAC is for keeping; MP3 is for the car, the old player, the USB stick for a friend. Encoding MP3 directly from lossless FLAC is the right way to make one: the encoder sees the true signal instead of another codec's leftovers, and at 320 kbps the output is as good as the format gets. Your files stay on your machine throughout, and a bitrate control sits under More options for when smaller matters more.

A 3-minute FLAC around 16 MB becomes a 7 MB MP3 at 320 kbps; at 192 kbps it is closer to 4 MB.

Questions

Is FLAC to MP3 better than M4A to MP3?

Yes, meaningfully. From FLAC the encoder works on the original signal; from M4A it re-compresses an already-lossy file and the artifacts stack.

Which bitrate for a car USB stick?

192 kbps holds up well in a noisy cabin and doubles how much fits; 320 if space is no concern.

Do tags carry over?

The audio converts; MP3 tagging differs from FLAC's, so complex tags may need a tag editor afterwards.

Is my library uploaded?

No. Every encode runs in your browser.
