there is no universal answer to your question. Personal preferences vary a lot. For me being at home with a reasonable income is the most important.
Regarding the types I would go for the command. Only if the other option were a 777 or similar would I give it a second thought. Nowadays the market is full of cheap cadets for the320/737. Saldy experienced F/os lost their value.
Getting command on the other hand is the best part of a flying career.
