Your set up sounds entirely plausible. I'm going to make a few points you need to consider in advance.
However, do consider what commitments you have on weekday evenings, and how this will impact DDog; I'm of a similar age but single and that was probably the biggest impact on my lifestyle when I accidentally acquired PestDog. You won't be as badly affected as I was as your circumstances give you a lot more leeway, but think about anywhere you go outside of the home (days out, pub, nights out, sports clubs etc etc), whether or not the dog can come with you, and what your plans will be for DDog. While I have been incredibly lucky in having a dog that will cope with a full day alone (I put a dog activity tracker on him.... It recorded 5 minutes of movement in the entire day) many others will find that their dog has a degree of separation anxiety; at the extreme end they can't cope with 5 minutes alone and will be destructive if left alone.
Consider if you are happy with lots of grooming; if not get a short haired breed.
Consider how much exercise you can give the dog each day - this is another major time sink for me as mine needs a minimum of 2 hours brisk walkies per day or his behaviour suffers and I'll regret it the following day - admittedly that's unusually high for most breeds, but it's par for the course with a Jack Russell X. Equally, how much exercise can your parents manage? A tired dog is a good dog...
Are you likely to have children in future? How will your child fit in with the lifestyle that your dog needs? I ask it in that way because the dog was there first and its needs will still need to be met; rehoming a dog because you've got a new baby is pretty low. It's a good job I never really planned to have children as my dog's exercise needs, combined with FT work, being single and no family locally mean I would really struggle to manage a child too. DDog's fear of motorbikes (he's reactive to that one trigger) means I couldn't safely manage a toddler and DDog when he sees a motorbike; it's a work in progress but he will lunge and snap, and on a bad day he'll redirect onto my lower legs - I'm currently sporting a substantial bruise and a few teeth marks on my knee because I misjudged it / didn't hear it approaching in time. For a reactive dog, he's very, very much at the mild end of the spectrum, and if it wasn't for that he'd be perfect!
Find good quality training classes, and go pronto once you get DDog. I grew up with dogs and thought I knew something about dogs. It turned out it was a massive learning curve, but I found training classes invaluable. Quality varies enormously, so look for someone APDT or IMDT accredited, Dogs Trust Dog School etc
How old are your DPs, and how old will they be in 10 years? Would they be able to cope with something big and bouncy? What if it pulls on the lead in the early days? DF is lovely and PestDog adores him when he goes for boarding, but it has taken months to get him on board with even the most basic of training stuff, like taking a packet of treats out with him on a walk for recall purposes. Consistency will make everyone's lives much easier. You may have DPs who are willing to listen and don't always assume that they know best despite never having owned a dog themselves.
Get good quality pet insurance - PetPlan lifetime is frequently recommended on here. It can be pricey because the cheap ones offer insufficient cover. As I'm in London, mine is an eye watering £48 per month for a 2 year old cross with no pre existing conditions.
The Kennel Club breed finder is a great way to get you thinking about what factors you need to consider, and the sorts of breeds that might work; of course it does not tell you about individual quirks or that perfect mutt at your local rescue!
