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
