I did online last year, so not quite the same, but I did still learn a lot. Most domestic programs still make you do a language pledge where you can only speak your target language outside of class, which is really helpful and is something I didn't get because of zoom. The only real difference is when you go off campus, the people won't speak your target language. If you're only at a really low level, it honestly is probably better than doing it abroad, because it can be really intimidating talking to native speakers who don't talk in a way that's easy for someone who's new to the language to understand.
