Pretty general questions, but I try to answer your question.
I don't know what the purpose of your image is, but installing
development tools like boost-dev or gcc (I guess that is what you mean
with cpp) makes your image automatically a lot bigger, I would suggest
to put devtools into a SDK, which could be shipped separately.
Next thing you can do is to analyze the what is actually so big in your
image, e.g. by creating a tar.gz of the image, unpacking it and browsing
by 'du -sh *'.
You can get the package/recipe to a file by using 'oe-pkgdata-util
find-path <path>'.
In the identified recipe you can look for PACKAGECONFIG or OE_EXTRACONF
switches that you don't need and disable them.
As said, I don't know what the purpose/environment of your image will be
like, but you could also consider to use a different fs-format like squash.
In general if you want small images preferring musl over glibc and
systemV over systemd is something that you could consider as well.
TL;DR
1) move to SDK
2) check PACKAGECONFIG switches
3) same as 2 or consider something "smaller" like lxc
4) same as 2
5) same as 2
6) same as 2
7) move to SDK
8) same as 2
