Posts for signage and fence

I plan to use 4"x4" white vinyl posts with white vinyl caps for my signange and fence.

Option A. Should I use “hollow” posts such as this…

Option B. Or should I use posts with wood on the inside such as this…


You need the wood or the sign won’t have anything to be fastened to. The vinyl is just so you don’t have to paint and re paint. Your 4x4 will also need to be 18-24" longer than the vinyl because it needs to be in the ground. Preferably with a couple bags of concrete.
