Address this with your direct boss:

Have a one-on-one discussion with your direct boss. Don't make it too formal: for example you could have a chat about this around a coffee or lunch, so it gives you a comfortable, friendly environment to discuss in (no point going in with HR and a copy of your job description at this point).

Since you have been in your job for a month, this is a good time to simply say to your boss "I would like to catch up with you on how things are going and get your advice/thoughts".

Be honest: tell him how you see things, the fact that you love the web content work and that you are really keen to focus only on this. Ask him how all the other stuff fit in with your job (the one you were hired for). Be candid about what you want to do and your ability to do it.

Gauge his reaction and ask him for support : it's normal you don't feel able to say no to these other bosses, and it's your direct boss's job to assign your workload. The other thing is to look at how this may impact your ability to perform your official duties: is this other stuff taking too much time from you at the detriment of your web content work? If yes, then this is impacting your boss's performance too.

Before you talk to your boss, consider also the following:

It's actually a mark of recognition of your professional abilities and potential that you are already being asked to create strategies and present in front of senior execs. Are there tasks that you would actually enjoy doing if it was formally recognized as being part of your job and/of if you were getting support for it (like dedicated time assigned to it)?

Look at the company culture: in some organisations it's normal to ask people to work outside of their official duties; is this the case in your company and are other people in the same situation? If so, you will need to find a compromise between accepting enough "external" work to fit in this culture whilst not letting it affect your ability to do and enjoy your original job.
