There’s an app I’ve come to like called sharchive. Can just share whatever link I want to open in archive.org or archive.is and I use it a lot for pay walled sites.
Simplest way for managing reddit links encountered in search I’ve found is just getting Stealth from the f-droid store and set it to use a teddit instance and open reddit links by default. No ads. Uses a reddit front end so less info for Reddit too over visiting it directly and times when you click search results without thinking.
