Can you provide hight quality images?

For some reason it’s not allowing me to attach another photo

If you can't add a photo to your original post, add it in a comment. Wait until the image is fully uploaded before submitting.

It’s not allowing me to view my entire gallery to select a photo. Maybe because I’m using the app.

Typically you would want to know you want covered soffits prior to installing the siding, as a vinyl/alum soffit needs a channel against the wall to hold it (e.g. 'F' profile), or a solid panel needs some blocking. Possibly same on the fascia if it is wrapped in trim coil.

Right now you have open rafters (or trusses) at both the eave and rake overhangs. The rakes do not need vents, and the question for the eaves is whether a birdblock has been installed between rafters (or trusses). Then, are there higher vents already installed (e.g. ridge vent or box vents). And to even back up a bit, whether you have attics.

We are doing stucco. Of course this is something that wasn’t on our plans that we learned about after the roof was up. I do believe we have ridge vents or maybe box vents. They’re round and along the 2 sides of the house. This was all that was included on the plans unfortunately and we knew no better.

Sure looks like dark blue horizontal lap siding. Back to better pic comment.

Let me figure out how to get pix posted.

Actually pic doesn't matter. If you are questioning the material, you can use vinyl or alum panel slats, solid board, or even stucco. If you are questioning the venting methodology - what I thought was painted white rafter tails may be the horrible pic instead - but if it is, a good assumption is there are bird blocks which would block soffit venting.

Aesthetics is directly related to your budget here, functionally any material can work/have vents installed to work. The look you want for the underside of the open porch roof may dictate the material for the entire house.

The important thing is to have a vented attic. In a passive situation, a chimney effect is created where cool air is drawn in low (neat the eave or soffit) and warm air exits high (through a ridge vent or can vent or gable vent). If there is no soffit and the rafter tails are exposed, there should be a vent at the frieze board.
