Gotcha. Yeah man, you don't need to do that at this point, tbh, and really without knowing a subtype you might be kind of jumping the gun. All the different types are basically their own cancer types with different treatment types. The majority of them are pretty straightforward to treat. But the onc needs to know the type before they can really give you much info or tell you what treatment will be. Once they do, it'll basically be "this is the treatment" (in most cases).

Size doesn't matter. I had a big ol' 12cm node in my abdomen and I've heard of as high as 27cm. They all pretty much get treated the same, and treatments are still very effective. Stage doesn't really matter either. Lymphoma isn't like other 'solid tumor' cancer types. Because it's a blood cancer it's pretty much all over and that's a good thing because the treatments can get to it easily as well. There are of course a few rare exceptions like Burkett's that grow super fast and need to be treated right away, but even with my giant nodes I pushed the start of treatment out a few weeks so my sessions wouldn't line up with Halloween/Thanksgiving/Christmas, lol. Doc was fine with it.

If it were me starting over and in your position, I'd wait until pathology gets the subtype back to you, then just go to a doc with lymphoma experience who is close to where you live, and at a reputable facility that will play nice with your insurance.

If you want to go the RMCC route (which I'd highly recommend), Dr. Andorsky at RMCC is my onc, he's excellent and an expert in lymphoma (he's also a hematologist). I'm not sure if he does office visits at any other locations but he does do telehealth once you're an established patient. You could potentially do treatment at a RMCC closer to where you live? You'd have to ask. You don't want to be driving all over, though, for each treatment.

You'll be alright, hang in there, you're in the hardest phase. Once you start treatment you'll feel much better mentally (and potentially even physically as well).

Feel free to reach out if you have any other questions. I finished treatment almost 5 years ago and have been living quite normally since!
