就: what are the top 3 meanings by usage
Chinese Grammar Wiki classifies the use of 就 into A2, B1, B2, and C1 levels (from easiest to hardest). Begin with the easiest level (就 as 'then', i.e. your 8th entry) – I believe this is its commonest use. Do not bother with harder uses of 就 (e.g. your 21st/22nd entry, which is labelled level B2 on the site) for the time being.

Sometimes you need to learn 就 as part of a word to make sense. E.g.: 就算 (your 11th entry), 就近 (your 13th entry). Sometimes, as part of a sentence construction, e.g., 一～就～ (your 7th entry).
