Can I get LMDE with xfce instead of cinnamon? And more LMDE questions

For those who don’t know what I mean:

• LMDE = Linux Mint Debian Edition, https://www.linuxmint.com/download_lmde.php
• xfce and cinnamon = desktop environments (DE)

target hardware for LMDE is an 8 year old nuked mac notebook with an intel chip.

I’ve always used xfce because it’s easy on the hardware and I don’t care that much about looks, but functionality.

I’ve never used cinnamon and I don’t know if it’s going to slow the notebook much.

Neither do I know if I can install LMDE and then change the DE to xfce.

Is LMDE being updated like the other mints? LMDE is version 6, whereas the other DE are version 21.3
