That's weird. I'd have to assume from the scores that Premier is GPU accelerated but Photoshop isn't?
PS is GPU accelerated, but not in the way most people expect: the biggest gains come in the form of UI acceleration, but for this even a relatively basic (but modern) GPU will do fine. There is also accelerated compute on PS, but that's on a case by case (depends on the tool, filter etc). On the other side, PS is traditionally a CPU Single Thread performance lover. By far the biggest improvements in quality of life in this software come from having a strong ST performer: from working with many objects to saving large files, ST perf will matter a lot.
I assume the OP is gone, and the brief of "Adobe Suite" did not help much with priorities, but given the budget my recommendation is similar to
@Seba 's: use the $300 to buy something like
i3 12100 + MB + 32GB of DDR4. The jump in CPU ST performance will be massive, the iGPU has a modern Quicksync implementation useful in video editing and is strong enough to be serviceable in Photoshop, and the DDR4 memory is still very cheap at the moment. The CPU & RAM should be around $180, this leaves $100 for a new motherboard. There's also some breathing room in case the OP lives outside US and VAT applies. This system will be quite usable in Adobe considering the budget, and has room to expand later with a modern GPU and/or a much more powerful CPU (in term of core count).
The same can be done with an AMD system, although that would limit the OP at socket AM4, as AM5 APUs are too much for this budget. On AM4 I would try to build something around the
5600G while still going for 32GB DDR4 and then getting the best motherboard for the remaining budget.
