Joplin runs on both Linux and Windows and can be synced via their own cloud, Nextcloud (selfhosted) and other options that i forgot. Joplin is more focused on markdown notes, but it also has a drawing feature, but i haven't used it much so i can't say much about it apart from the fact that it exists. try it out. If it does not work, use Xournal++. That is mainly focused on written notes. However afaik it does not have a note sorting system so you would have to do that in the file explorer.
