It's great to spend more time with your parents before they die and they're gone forever, leaving you to do whatever without them for the rest of your life. Other benefits to living with them noted. Personally I think that matters more than prestige but it also depends on your ultimate career goals.
As far as loans, I've gone into detail elsewhere, but I would just do income based and PLSF and call it a day. Unless you can really make headway on those loans at any point before being an attending, I see no point.
Too many people have something go wrong with life where in hindsight they shouldn't have worried about it, should have lived a regular life. As long as my payments are reasonable compared to my income, who cares if you pay on it for 20 years? Who care if it's a million dollars? I only care about having money in my retirement, a house, something to leave to the kids. It's a second mortgage, but if you can afford the two and live decent, save, and save for retirement, which doctors can.
It's a fallacy for many to try to live a debt-free life these days, at least I would think so until you get attending checks and can figure out some way to do that.
A couple reasons I say all this:
I know a physician who busted ass to pay off all their loans in 10 years. Then they got a terminal disease and died within like a year, leaving their spouse and very young child to fend for themselves. Might have been better to spend more time with family, pay less loans, live better, save more in savings in trust for the kid. Student loans die with you.
Another physician had an inheritance in trust for them. They had massive student loans. Partner suggest they use all that money to pay off student loans, physician balked at the idea. Physician was disabled in residency, now has no income. Student loans discharged, money in trust still available, thank God they didn't use it to get out of their loans. Also grateful they didn't use what little stipend they had for loans, and instead lived a little better on it.
Round and round it goes. When I took on student loan debt to pursue an education I could leverage into a higher salary, I just saw it as the opportunity cost. Loan payments, until the day I die (facetious) are just cost of doing business, it is the overhead. It's like living on the street, and then starting a multimillion dollar a month business where you have a million dollars a month in overhead. You're still getting ahead even though you have expenses, so it's still worth doing. I have no problems having a salary and paying on those loans until I don't work anymore.
The issue is that people look at all the "extra" money they'll have/save from interest paying in the short run rather than the long run. The issue is that there is no way to know, as I've illustrated, if you'll ever see those savings on interest. The only money you have is what you make today, and the only money you have for tomorrow is what you save and safely invest.
Any financial advisor will tell you not to sacrifice all savings to bring down debt, the above scenarios being simple examples of why, there's more reasons than that. The key is a balance. That isn't to say there aren't other ideas about paying down debt, or that you shouldn't try to pay down debt.
For me, I calculated I would have had to pay $30K a year just to avoid capitalization, just to keep up with interest, not even pay down principle. Meanwhile, on my IBR my loan payments were like zero or $200 a month. I decided I'd rather have the money in the hand.
Other people are smarter about finances with me, more highly value paying less interest over the life of a loan, and can leverage that financially, and some people are just more conservative about getting what they can now and kicking the loans down the road, like me. Ultimately what it comes down to in finance so many time, is your own values and how risk averse you are.
