I found a nice Kanji radical character cheatsheet that's categorized by stroke count.

"Remember, kanji isnʼt made up of individual strokes, itʼs made up of radicals. If you learn by strokes, you have to remember 5, 10, 15+ plus steps. If you learn the radicals, and put them together like building blocks, youʼll only have to remember 2, 3, or 4
steps to put together a kanji."
