Spanish speaker here, Franciscas most commonly are called Pancha instead of Paca

At least in Brazil we use our names, sometimes with the pronunciation in the language we're studying. No need to use a foreign name.

We chose from a list where students with earlier birth dates got to choose first. Perhaps a consequence of small school district combined with less commonly-learned language, but after the 3rd year with the same teacher, we tended to revert to our real names, just pronounced with an accent.

Spanish: we got to choose, most people chose something close to their real name

Mandarin: my teacher’s Taiwanese wife painstakingly came up with names for us that were close-sounding, or at the very least had the same first letters. It was very cool of her to do

In my intigratuon course, we try to pronounce our names with the appropriate accent.

We just used our regular names!

Depends on the teacher. We had both kinds.

In all language classes I've been a part of we just used our names lol :3

We used our regular names.

Spanish: pick your own name
Japanese: must use the Japanese-ified version of your name, eg Smith -> Sumisu, and people will usually refer to you by last name.

In retrospect, it was kinda strange to pick names in Spanish. It would be really strange / unacceptable to just pick a random Japanese name for yourself, and I've heard that it's really rude to pick a name for yourself in American Sign Language. I wonder why it's so widely accepted to do so for Spanish.

We got to pick, pending teacher approval.

I was Burrito in Spanish.

Most people chose their name, sometimes choosing a name similar to their real name, sometimes choosing completely different names. The only time I saw someone assigned a name was when their name conflicted with another student's.

I chose Rebeca/Bequi :)
