Migrating from Brave to LibreWolf. Any suggestions or precautions?

I've recently downloaded Librewolf and I am planning to transfer my data from Brave to it. I am a privacy aware user but I haven't had much experience in using Firefox directly. I have Firefox installed but I have some other old things stored in it (accounts, cache, bookmarks etc.) that I do not want to disturb, nor do I want to use as my default browser. I thought Librewolf would offer a more private and better version of Firefox with a clean slate.

Are there some things to keep in mind while transferring my workflow from a Chromium based browser to a Firefox one? Are there some things to keep in mind specifically for Librewolf? Would I need to change my browsing habits?

Some points about my browser workflow to help you better judge what I may need :

• I have some accounts saved in my previous browser e.g. Google, Discord, Spotify etc. that I don't use really much, but require them regardless
• I use uBlock Origin and SponsorBlock as the only extensions
• I mostly do light casual browsing e.g. searching for stuff in DDG, streaming video/audio, communication etc.
• I have been recently avoiding proprietary software and websites in favour of privacy-respecting alternatives and frontends, to the best of my abilities
• I occassionally use Tor for anonymously working in websites that I have logged onto in my main browser
• I have had Brave installed on my Android phone too, synced with my PC
• I installed Mull in my phone in the hope of pairing it with Librewolf while avoiding creating a Firefox account if possible
• I use Proton VPN (free tier) whenever I use my browser(s)

Sorry if I may be asking obvious questions or doing things blatantly wrong as a privacy respecting user.
