US Immigration from Uruguay

Hey guys. I'm just kind of overwhelmed right now after reading so many stories about B2's being rejected for non-engaged couples and any advice would be greatly appreciated.

I'm planning on visiting my girlfriend for the first time around December so we can spend Christmas together. We've been in a long distance relationship for a few months now. My country (Uruguay) has a low refusal rate (around ~3% I believe?) but I know that mentioning a girlfriend while applying for a tourist visa might be considered a red flag (which is funny, because I don't think it's logical to apply for a K1 without meeting in person first), and they might want to be completely certain about my ties here so I don't overstay. Being an 18 year old student I don't have a stable career, I'll enroll in college here soon and I'm going to visit before classes start, so maybe that could be interpreted as an obligation to come back? My family owns property here which, I think I'll inherit some eventually, so maybe that can also be considered a strong tie?

She's financially stable (she's 21) and lives by herself, but my family is also doing fine (my grandparents are paying for the trip and expenses) so I don't have any logical reasons to overstay given the fact that we might pursue a K1/CR-1 in the near future (once I return) and my quality of life here is good. I'd appreciate any advice or tips

My earliest accepted filing date is 7/11/2020, I wanted to go ahead and get this thread started if possible! I'm hoping that our wave will not be as impacted by COVID since USCIS is resuming operations June 4th.
