How to identify Dative and Accusative verbs?
Is there a website that lists a ton of German verbs and identifies them as either Dative or Accusative?
Perhaps a different resource?
My stack of verb note-cards is getting quite large and I need to annotate whether the verbs are Dative or Accusative.
Especially since I write three verbs per card.
I just finished Present 3.

The best way would be to learn a verb with the required grammatical case together. So you will also learn different meanings of a verb.
Some examples in German for the verbs "einstellen" and "vorstellen"
einstellen => jemanden einstellen (to hire someone); "jemanden" = Akkusativ is required
Das Firma stellt ihn ein. = The company hires him.
einstellen => etwas einstellen (to adjust something OR to shut down something); "etwas" = Akkusativ is required
Ich stelle die Uhr ein. = I adjust the clock time.
Die Firma stellt die Produktion von Uhren ein. = The company shuts down the fabrication of clocks.
vorstellen => jemanden jemandem vorstellen (to introduce someone to someone); jemanden = Akkusativ (the person, that is introduced); jemandem = Dativ (the person, to whom someone is introduced)
Ich stelle meinen Freund meiner Familie vor. = I introduce my friend to my family.
(This is a verb, where some learning sentences in Duolingo are wrong for years now!!!)
vorstellen => sich etwas vorstellen (to imagine something); etwas = Akkusativ; sich = reflexive pronoun, requiring the Dativ! (Akkusativ is already taken by the object, that is imagined)
Ich stelle mir etwas sehr schönes vor. = I imagine something very beautiful.
If you are serious about learning German, you should get a good dictionary which lists the cases and prepositions that go with each verb. I recommend the Langenschedit Großwörterbuch Deutsch als Fremdsprache.
