Hello,
1 - Market mode
You should always use "Store paid directly" unless you're only using "collect on delivery" and your vendors receive the money directly from the customer (hand by hand)
In all other cases, you must use "Store paid directly". Including payment methods with HikaMarket support.
2 - Vendor price with tax
It means that the fee is applied on the price with taxes ; which is a very very particular case.
3 - Vendor payment content
Where did you read that ? Without a context I can't give you an answer.
4 - Stripe Connect is an adaptive payment methods.
It means that your vendors, while "connected", receive directly their payments (minus your fee)
