Your GeForce RTX 4070 Ti Super can only decode 10-bit 420 HEVC. Your CPU has a Intel UHD Graphics 770 which can decode 10-bit 422 HEVC. I have a similar iGPU but don't find the performance all that great in VEGAS.
My suggestion would be to find sample footage from this camera or a similar one online and test it before you buy the camera (or if in the store they let you shoot a sample onto your SD card do that).
Recently I started to use Panasonic X1500 and recording in 4K-60p 10bits (both mov & mp4):

Editing the footage in VP 22 (encoding to 8bit), however on my system (see my specs) I cannot do it without proxy at all (preview framerate is just a few fps). With proxy I can edit it with full framerate but only if using auto preview resolution :(
Going to upgrade my CPU/MB/RAM this weekend. Not expecting miracles as by reviews the new CPU it not much faster. So later I will most probably upgrade GPU as well.
Also, RAM usage is very high and I'm still having some random crashes (I found it much more stable when I disable GPU decoder) that I did not have when editing my 1080-60p footage from previous camcorder.
@ChasMc I use an Intel Gpu in a 4x slot to augment 10 bit decoding. They are not very expensive. If u can get your hands on 10 bit hevc sample clip and make available am happy to give feedback.
@ChasMc I found a good difference using VP21 using the Intel GPU set in I/O either ON or OFF.
However using VP22 b248 shows such improvement in playback with Intel GPU ON or OFF that my VP 22 test is redundant.
The sample I used to test was previously available here (user AVSupport) and would really try any PC. It's the Sony A7SIII Hevc 10 bit 422 with no P frames all B frames.
My computer specs are listed below. I shoot 4K 10 bit 4:2:2 150Mb/s MOV Panasonic, but AVC and HEVC. Some effects play back ok, others, I have to change the Preview to something has acceptable playback. I'll try effects, and if playback it really not great at all, I'll do that at the end of editing.
@ChasMc The reason why in using VP22 that there is good playback with Intel GPU not selected for decoding in I/O is that it IS being used as the Taskmanager displays in Video decode1. Not issue with this, VP is simply seeing the decoding capabilities of Intel GPU and using it although it's not selected in I/O.

It is possible you do not have decoder selected in dropdown, but option 'Enable QSV Encoding and Decoding (where available)" is ticked.
johnny-s, I tried your sample. On Best- full, it ran ok with a little jurky when moving. Tried a simple cut in it with a 1 sec. transition. The transition was poor. Tried preview - auto, wasn't very smooth when you were moving.
@ChasMc That's a really difficult clip to play at anything near 50fps. Your result on Best/Full sounds very good. Im guessing that camcorder media won't be as taxing.
@johnny-s I downloaded your sample. I was able to play back the clip with Preview set to Good>Half and getting consistent mid 40's playback. All the heavy lifting was done by the CPU. The GPU was just there to watch what was happening....
@johnny-s VP22 (248) That sample played back at 50fps but cut in half & a short crossfade applied it stuttered across that transition. With proxies Preview (Full) it played fluid full 50fps even across transitions, I could do whatever i wanted with it..

I unchecked that first and it made no difference. I still had Intel decoding equivalent.
Then I ran Taskmanager with it still unchecked and I am getting Intel decode1 benefit.
Ok. I think the decode1 is odd. i.e. an anamoly in so far as it's giving a readout graph for Intel GPU when it's not selected for decoding. At the same time the "decode" (not "decode1") shows no decoding graph when Intel is not selected.
The simplest way to confirm is to physically disconnect the Intel GPU, I did that. I marked out the AVSupport clip in 1 - 6 second markers. Total duration is 26 seconds.
With the Intel GPU physically disconnected playback at Best/Full only hits 50 fps immediately after the 6 seconds marker.
With the Intel GPU in use and selected for decoding then playback at Best/Full hits 50 fps immediately after the 1 second marker.
I suspect that 'Enable QSV Encoding and Decoding (where available)" is only applicable to iGPU's.
I still get 50 fps just after the 1 second mark whether 'Enable QSV Encoding and Decoding (where available)" is checked or unchecked.
Meant to add that with Intel Gpu not selected for decoding in I/O playback at 50 fps takes place just after 4 seconds mark.

I'm thinking that your camcorder output may be not as difficult to play as this sample.
