Daas, besides that fact that I believe a kohen not marrying a giyores is derabanan today, not discussing halacha here, I said that if there is no halachic issue after you talk to your posek (i.e you are a levi for example) then go ahead and marry a giyores.
There is no need to feel bad about it for being “less kodesh” or something of the sort. My take.
