I'm a little surprised nobody has mentioned Zim: https://zim-wiki.org/ https://zim-wiki.org/ From their site: " Zim can be used to: Keep an archive of notes Keep a daily or weekly journal Take notes during meetings or lectures Organize task lists Draft blog entries and emails Do brainstorming" Zim itself is a good desktop application and Markor is a good mobile client for it. Sync can be done via nextcloud, dropbox etc. I'm not 100% on the state of the windows support, but I use it daily and it is great. It coexists nicely with version control, too.
