Hood Venting Advice

the microwave/vent in my new place failed. I pull the unit down and found that the vent from the microwave was barely attached. (hence all the grease on the cabinets 🤮

I'd like to install a venting hood and go with a countertop microwave.. I'm not sure what the best option will be to connect the new wall hood to the existing vent. I'd love to be able to seal/tape the connections properly.. I do have the cabinet above free, and though about going up first, then into the wall... Any thoughts?

(the wall duct is 3-1/4" x 10")
