Presentation type is usually not based on reviewer score, but rather the type of paper you're presenting.

99% of your resume boost through this achievement comes from the fact that you have a first author publication at EMNLP. When you apply to jobs in the future, nobody will care if you actually presented in person or online. It only matters for the connections you make at the conference itself - which are way more important at later stages of your career, not so much as an undergrad.

For things like applications to PhD programs your GPA still matters. Take that into consideration if you think your exam performance might suffer as a result of attending EMNLP in person.

The in-person EMNLP will certainly be large, but I also suspect a sizable online crowd as well, because Abu Dhabi is far from Europe, China, and NA, and has received a lot of criticism for being an LGBTQ-unfriendly place. While it's easier offline, you certainly can make a lot of connections during online events as well. I especially found poster sessions in GatherTown to be fruitful. If you study the program carefully to attend virtual posters of researchers you want to meet, it's a viable way of networking.
