Will my rankings be affected if I change domain from http to https and force redirect?

Im in the process of launching a blog. The blog will be for global audience. If I wanted to target a more specific region in the future example UK would it be advisable to launch a separate blog for the UK market or how could I regionalise the posts if I kept blogging on the Global blog.

I have a TLD .com and 3 microsites in different regions with the specific ccTLDs. The structure is the same and most of the content is the same. Does Google regard this as duplicate content?
