Why convert
MP4 — the most compatible video format: plays on any phone, browser and TV. 3GP — video from old feature phones, usually at a small resolution. Use it when a program or device asks for 3GP specifically.
What changes in the file
The video is re-encoded; at High quality the difference is not visible. One video and one audio track are carried over; subtitles and chapters are not. 3GP uses an old codec, so at the same quality the file is larger than MP4.
Which settings to pick
If the file has to fit a limit, set File size: the quality is chosen for you. For messengers choose Smaller file and 720p; for editing keep High and the original height.
