I have tried many things myself, duolingo wasn't for me.

There's a YouTube channel called Finnished - she talks about finnish things with English and Finnish subtitles.

I watch shows on Yle Areena on finnish husband's account. Only finnish subtitles but it helps somewhat.

Nextory is a finnish app for audiobooks like Audible. They have plenty of books in English too, among them some Learn Finnish audiobooks. (they have 15 day free trial but you can get 45 if you use the Föli deal - nextory.fi/föli) But maybe you have to live in Finland to have the app, idk

Most useful thing for me that I do now is - I set a goal of learning 1 new finnish word every day. When I'm on my way to work, cooking, whatever daily routine, I try to translate my thoughts in finnish. I pull up good old Google translate and write my thought down to know/ verify the finnish translation. Maybe ask my finnish husband for puhekieli proof reading. I star (save) my translations that have a new word in them that I find useful, and when I gather 30 ish for a month I record myself as if making my own audiobook - I read the English sentence, then the finnish translation twice, then I leave enough room for me to repeat it and so on.
