Because FLV supports H.264 just like MOV does, the video stream can be carried across without a quality-costing re-encode.
Embedded subtitle tracks will be lost. MOV can carry them inside the file; FLV has no place to store them, so export them separately first if you need them.
Only one audio track will be kept. MOV can hold several, for example alternate languages, but FLV supports a single track.
Anything above Full HD (1080p) will be downscaled, because that is the practical ceiling for FLV where MOV reaches 8K UHD.
At 1080p, MOV typically runs around 35 Mbps while FLV sits near 4.5 Mbps, which is the main driver of the size difference you will see.
This page converts MOV video, stored in the QuickTime container since 1991, into FLV, which uses Flash Video and dates from 2002. The codecs each container accepts decide whether the picture has to be re-encoded.
MOV comes from Apple and dates to 1991. It usually holds H.264, H.265, or ProRes video with AAC, ALAC, or PCM sound, and those streams set the ceiling for anything converted out of it.
FLV comes from Adobe (Macromedia) and dates to 2002. It holds H.264, Sorenson Spark, or VP6 video alongside AAC or MP3 audio, and every major platform needs a media player such as VLC to open it.
