God, what a relief to see some other women remotely bothered about this. I think OP and ninagleams and loads of others have said it all, really. Most of my friends have simply taken their husbands' names for themselves and/or their DCs, and that's their choice, but I am sometimes made out to be a bit of a nutter for thinking any differently, and it's hard to explain my own reasons without sounding like I'm passing judgement on others who choose differently.
I too did a PhD and then spent about 2 years gleefully saying 'it's DOCTOR, actually' whenever the inevitable 'is that Miss or Mrs?' question came up, but then started to feel like a bit of a ponce once the excitement wore off. So, back to Ms, which hasn't been a problem but then I haven't needed a CRB check. But I'll fight the good fight with them, if I ever do need one.
I have my mum's 'maiden' name because when my parents divorced she switched back and I switched with her, and I have no wish to change it ever again. DD has a double-barrelled name, which DP was actually more bothered about than me - he was quite affronted at the idea that my name would simply wink out of existence for our children. We aren't married
(CAUTION: UNWED MOTHER ALERT!!)
but if we were, I would still be Ms Ourraquel, and our children would still be double-barrelled. I agree it's not an ideal option, but it's the best one we could come up with.
FWIW, some friends of ours combined their surnames when they married, to make a new surname which everyone could have. We tried that but it sounded either like a porn mag or a budget supermarket depending which combination you went for. And a male student of mine did take his wife's name when they married. Although his wife's name is also a very nice woman's first name, so when I was told that he'd changed his name to very-nice-woman's-first-name, I spent a very confused week thinking he'd had gender reassignment surgery. But that's another story. And I think he is a hero for taking his (lovely) new name.
Also FWIW, my DD loves having both of our names as her surname, and even though she's only 2 she will proudly tell it to passersby and explain that it means she is 'a bit Jewish and a bit Scottish'.
I'm sure she'll hate us for it when she's older, mind you. But they have to get their ammunition from somewhere.
