Welcome to the Hook Productivity Forum, @QpUc8K . Inkdrop is of course an electron app, which poses special challenges. As you noted, there’s no AppleScript support in it. Perhaps the dev could do some bridging along the lines of [Enhancement] Applescript API · Issue #4418 · electron/electron · GitHub I’ve brought it up with them here Request to make Inkdrop Apple Scriptable - 
Features - Inkdrop Forum, and Adding a hyperlink to a note - #3 by Luc_Beaudoin - 💁🏻♂️Support - Inkdrop Forum but didn’t get traction. Hopefully the folks behind electron itself will make automation integration easier.
Re other note taking service and apps, there is Roam by RoamResearch (@Conaw sometimes contributes to the forum here) which is a web service; and Bear notes, which is an app. And a lot of other apps of course that have automation.
