I too created a spreadsheet for each donor we were considering, featuring columns for each of the data variables we deemed to be important. Each row represented a different donor. It is time consuming to enter all the info, but once done, makes it much more simple to review and start to eliminate donors.
Good not to overthink things, notwithstanding how important a choice this is. That said, we all know people who've had babies with red hair that is traced back to a grandparent, freckles, etc. All to say that even when women use their own eggs and their DP/DH sperm, their offspring can pull-in threads of DNA and corresponding attributes from farther back in their family lineage. Most will end up telling you that "...your baby looks just like you/your husband/mother" etc regardless, because s/he will be yours.
Best of luck to you making this choice.
