first of all not all frameworks are the same, so trying one framework will not give you a definitive answer weder frameworks are right for you or not, but everybody starts somewhere so you could first find a specific category per se, "mobile development", "Web applications", etc,  and then see al the frameworks about that specific category, you can now choose a framework of that category.

To choose which framework within that category you could choose the one that uses a programing language you already know, but don't limit yourself like that, if you are willing to learn another programing language specifically for that framework, you are free to do so, if you really don't want to choose a framework, you could choose it at random or the most popular one which guarantees you, that you are learning something relevant at that moment
