What bitrate should I use?

320kbps gives near-lossless quality. 192kbps is good for most listeners. 128kbps is fine for casual listening and podcasts.

Is there a file size limit?

No server limit. Large FLAC files may take longer to process.

FLAC files are lossless and very large. Converting to MP3 makes them 5-10x smaller for easy storage and playback on devices that don't support FLAC.

320kbps is recommended when converting from FLAC to preserve as much quality as possible. 192kbps is good for general listening.
