For selecting durations, you can use this --download-sections REGEX

Download only chapters that match the regular expression. A “*” prefix denotes time-range instead of chapter. Negative timestamps are calculated from the end. “*from-url” can be used to download between the “start_time” and “end_time” extracted from the URL. Needs ffmpeg. This option can be used multiple times to download multiple sections, e.g. --download-sections "*10:15-inf" --download-sections "intro"

As for the thumbnails, usually, when I download a Youtube Music album thumbnail, it is already squared. Before that, I used to use a specific hack, but I don’t remember how I did it anymore. Check this discussion, it may help: https://github.com/yt-dlp/yt-dlp/issues/429
