Thanks. You've already built GCC from source, which is a great start.
A good thing to try next (if you haven't already) would be to try
hacking in a warning that emits:
"hello world, I'm compiling function 'foo'"
for each function being compiled, and compile something with that...
and then do it again in the debugger, with a breakpoint on that, and
step through some of the code, as per:
https://gcc-newbies-guide.readthedocs.io/en/latest/getting-started.html#hello-world-from-the-compiler
The point here is to get you and your development environment to the
point where you can comfortably make a simple change to GCC's source,
rebuild it and quickly see the results of your edits (without having to
wait ages), and for you to get comfortable stepping through it in the
debugger.
Let me know if you run into issues (which could suggest improvements to
the guide).

FWIW I'm not particularly expert at the specific areas of GCC relating
to the two projects you mentioned, so hopefully others on this list can
give advice/mentoring with those.

I'm biased here in favor of my own subproject, the static analyzer; as
discussed in the recent "[GSoC][Static Analyzer] Ideas for proposal"
thread on this list there are dozens of RFEs against the "analyzer"
component in our bugzilla, many of which are relatively small. That
said analyzer is quite complicated, so I don't know if that's a good
first warm-up for someone who isn't planning to work on the analyzer
for their GSoC project.
We have an "easyhack" keyword in our bugzilla which you could try
searching on that. Unfortunately, people's definitions of what is easy
vary, and I don't think anyone's been curating that list recently, so
you might want to check in here with the URLs of the things that catch
your eye to make sure they're reasonable first projects.

It sounds like you have a lot of relevant knowledge; I hope we can find
you something you'll enjoy working on.
Let me know if you have any questions
Hope this is helpful; welcome again.

Hello,
we are delighted that you decided to apply for GSoC and that you have
chosen GCC as the organization.

Please note that both projects have already been discussed on the
mailing list. For information about the first one definitely have a
look at https://gcc.gnu.org/pipermail/gcc/2023-March/240833.html
The C++ traits project has been discussed at least in
https://gcc.gnu.org/pipermail/gcc/2023-February/240816.html
If you have any questions after reading through the above, feel free to
email the mailing list again.

Unfortunately, there just are not many "small" projects that a newcomer
would complete in "a day or two." I can only endorse what David wrote
to you in his email.

That looks like a nice course after which you are likely to be familiar
with the necessary concepts for GCC work.
Good luck!
