Hello, I’m having trouble finding a good equivalent for the word ‘so’ (or if you speak or have experience with French, donc) and wanted to know if I could get answers here.

Examples : E.g., Alitaka kuhamia Ufaransa [so] alianza kusoma Kifaransa miaka minne iliyopita E.g., Sikuwa na viambato vya kutosha [so] nilikwenda sokoni ili ninunue kingine E.g., Hakuwa na pesa za kutosha auende chuo kikuu [so] aliamua kufanya kazi mwaka huu E.g., Nilimsema Dada yangu (kwamba) ninakwenda kusoma ng’ambo Kanada [so] alinisema ningehitaji kuletea koti na mavazi ya vuguvugu

Niliandika mwenyewe sentensi hizi [so] mnaweza kusahihisha makosa yangu yo yote?

Update: Thanks for all the helpful replies!
