Hi and welcome! Somewhere in the information articles on the site I've an old one on getting two puppies at once... the general advice is, this is a huge challenge and the outcomes tend to be better when there's a year or so between puppies. I've had multiple dogs over many decades and only once took on siblings (or two puppies in close age). And I thought this was something I'd manage fine. But not only was it a HUGE amount of work -- as you simply must give each dog separate time of the same quality you'd give one -- but I realised after they both had passed away a decade later, that really, our bond with the two of them was never quite the same as we'd have had raising two puppies separately, with 12-18 months between adopting them. Not only will they bond in ways that WILL exclude the humans, but my solo time with a single pup the next time around was so much more enriching. And training, crating, toileting, etc all need to be done separately so it is twice the work. Often undone because they then focus on each other and don;t really pay attention to their people. Many dog trainers won't allow two puppies, owned by the same people, in a class at the same time because they are too distracted by each other.
There are many many articles out there on the pros and cons of two puppies and it's hard to find anyone with expertise in dogs that thinks two puppies is a good option. It will be fine, of course, but there's little benefit to a puppy to the relationship and something will be lost for the humans involved.

I actually think it's harder to have two dogs the same age who grow old together -- even dogs close in age mean you end up being limited by the senior issues (and costs) that generally descend at this point and losing two close together is also very hard (take it from me, I've had this happen many times over from having multiple dogs, many of them older rescues that came into rescue together).
I'd say that yes, you can make it work, but I'd also say, don't underestimate the enormous time and commitment for the first two years and really, ever after as they really should not be left to always do things together and never have quality alone time with the humans. And from experience, having had dogs for years and years -- I'd never do two puppies together ever again. Something is lost for the dogs, and for the people. And sometimes they grow up and don't get along precisely because they are too close in age and then you end up having to try to re home an adult.
Others may well have a completely different take but that's mine, from running a cavalier rescue and being a long time dog owner (and knowing many excellent dog trainers and behaviourists!
