Which programming language would be best for my interests..?

I'm struggling so much to decide which language I want to learn. I consider myself to be a novice since I haven't had much hands on experience. I attended my first hackathon for my college and loved it so much. I am extremely motivated but very confused because there are so many things i wish to do. Here are some examples and if anyone can recommend languages where my ideas canbe achieved with would be greatly appreciated.

I wish to create a wristband that can be used as a universal remote controller for smart tvs and can automatically connect my Netflix/ hulu etc to the tv. It would also have tiny controllers on the band. I'd want to make it look kindalike a the razer nabu but a bit different.

^if this is unrealistic, then

I'd like to make my own personal "fitbit" type thing that can record protein/fats/carbs/calories and have a barcode scanner on the wristband itself to count the nutrition facts (it would also have a up/down/right/left keypad to adjust serving size and quantity etc

I'm also interested in games. I'd like to make some for the VR but i do not own a VR. I'm also interested in making games such as an RPG/survival that can be achieved alone (for now id like to rely on my own self to hone my programming skills) I'm not interested in graphic design/animation so I'd buythat offthe asset stores offered by unity/unreal etc.

For now i am interested in making hardware which will use my softwares for fun/benefitting my lifestyle which would be really cool/useful to me. I'm just confused on where exactly would be the best spot to begin since there are so many languages (yes i plan to learning multiple for sure) but i have no idea what language would be best learned for my hardware type purposes.

Thank you in advance!
