[Advice Needed] Confused and no idea what to do - Freshman at an Eastern European country

WSO forum, I need your help.
I'll keep this post as simple and real as I can.

About myself:
I am a freshman at an Eastern European country. Major: International Economics and Finance.
Between school and university, I spent 3 years working in villages helping in innovation management, plus leading a large student organization and a start-up of my own.

Personal:
I am more sort-of a person who is willing to go for international travel etc.

Problem:

I am looking for Summer gigs this coming year - internships etc. Hoping to work in United States and/or Europe in the long term. (Personally prefer Europe more but its not an issue)
I can say I am pretty good at: research work, public speaking/presentation, both Excel and PowerPoint, general finance and economics etc.
I always thought I have interest in both Consulting and Banking sphere, but I cannot point out exactly what/where.
My uni, unfortunately, has no dedicated career office. and I don't have too many people to ask.

I find WSO forum to be such a gem, but all the talk here makes me confused: S&T, Hedge fund, Buy-side/Sell-side, Venture Capital etc. I read what these terms mean and sort-of understand but still it makes me very confused as to what exactly to choose in terms of career.
This could be detrimental since I am at a critical stage where I must know what to do and which door to choose.

In short - kindly help me understand the clear differences between such terms like: IB/Hedge Fund/Consulting etc.

Also, your personal opinion based on my post as to what you think might be a good fit for me.
(This can be a starting point for me as to research further)

Kindly help, I am very very confused here.

Thanks!
