The question is what does “learning the kanji” mean. To recognize words that use it? To be able to recite frequent readings from kanji in isolation? To remember the specific English keyword that WK/whatever system assigned to it? To write it out by hand?
Different language goals call for different aspects of learning the kanji, which in turn calls for different SRS setup.
If your initial goal is to just understand simple spoken language in familiar contexts and reply back (which I’d argue it should be), you can postpone kanji until later. You can even read middle-school manga with full furigana (e.g. Frieren) without them.
The next logical step is just elementary school first grade kanji + most common radicals + phonetical components (e.g. 生 giving せい・しょう readings to 性 etc).
Whichever shape your kanji SRS takes, it can very easily create a mountain of reviews, I’d be mindful of that and of the time you have available.
