I migrated from Evernote to Obsidian a while back. There's a variety of tools available to extract your notes and convert them. I am pretty sure the one I was used was Yarle: https://github.com/akosbalasko/yarle

+1 on Obsidian. Markdown is super nice to use and as for syncing it's open to BYO solution (it's all just markdown/text files!) or you can pay Obsidian to sync for you.

The Obsidian Importer is free and converts your data to Markdown that you can use with any Markdown-compatible app:
