XAVCS is in a mp4 wrapper, so yes that is correct.

No need for this, if your NLE likes XAVC-S...
If you experience slow working speed, you better convert to a more
edit friendly codec. But ProResHQ is much, much bigger than XAVC-S.

I've imported XAVC-s into Premiere, Vegas, Lightworks and Edius, they all seem to play it quite well.
If you need to do editing and still need to convert it, you could use avid dnxhd 36 codec (I mainly use Avid) or Avid h.264 800kps proxy mxf. pretty fast for editing.
For CC I have no experience with Xavc-s yet, with old crappy EOS h264 I convert to 16 or 32bit after denoise, not sure Xavc-s needs that.

Resolve and After Effects seem fine with it.

XAVC-S is a highly compressed long-GOP codec.
Nice to have smal files even with 4k/UHD but it will
stress your processors no matter which NLE you choose.
If (!) your NLE works fine with the files, there's no need to
convert prior to editing as most or all NLEs render their own
codec if needed after FX.
Nevertheless I would choose ProRes or a similar all-I codec
for editing purposes...

Use XAVCs
On a Mac (I have several pretty fast laptops and Imac/MPs) I just import into FCPX and apply a LUT if it is Slog, then just edit away, if it only needs basic CC then FCPX works great, then render out as ProResHQ or ProRes422 and I am done .I am sure the work flow in premier is the same. If I need major grading then I use Resolve 11. No need to ever transcode the apps take care of it. I am sure it works the same on fast PCs.
If you have a slower computer and no Fast RAID or SSDs in the laptop then you will have to transcode. So basically it is hardware a decision. If you have a slow system then transcode or even edit in proxy mode. If your suite or laptop works well with files straight from the SD then go for it, the results will be fantastic. We are so spoiled these days...

I also edit XAVC-S files directly.
I'm finishing an edit that's reasonably filter-heavy (it's a 5-minute 1080p video and the final render takes over one hour), my mid-range PC works fine with it (with all the filters on, scrubbing could be a lot faster, but that's why I get my edit lock first and play with color only in a second stage; I don't think a prores transcode would improve this in a noticeable way).

Which ever software you choose to use be sure to check if it works with the audio. The video works just fine with any app I have tried but the audio only seems to work on adobe products. XAVC-S is an mp4 but uses a non-standard audio format for mp4, wav I believe. As a result a lot of software can't handle the audio, Resolve is one that cannot if I recall correctly.
