2020 called and wants her easy questions back! ;)
Immunity to cold viruses is so prevalent, there is no chance the effect is pronounced, by now. It has been researched tho, so you may find some studies discussing the issue.

On the other hand, the cross-immunization to SARS1 and MERS is not surprising, since the mRNA vaccines were developed for these and modified for SARS2. (It is not a completely novel vaccine and "rapid development" was only possible, because a lot of basic research was already done on SARS1/MERS. Would have taken a lot longer to identify a molecular target otherwise.)
Actually...according to some studies it is.
