My path intro Hebrew proficiency...

First, get a foothold in Hebrew...

I highly recommend an app like Duolingo for getting a foothold in the alphabet. This is a low-cost, low-pressure way to make a little headway, and to feel a little bit comfortable within the Hebrew language community. (There are a lot of people with aspirations to learn Hebrew, some of them not that sane because of the religious implications.  Getting started with the aleph-beit shows a certain commitment and willingness to self-start which is usually welcome by the community.)

After that, consider an Ulpan either remotely or in-person in Israel...

Traditional ulpan (language school), i.e. for new immigrants, is a state sponsored series of 3-month long programs.  However, there are private ulpanim in Israel that will do shorter stints, and deliver content via Zoom.  I highly recommend enrolling in an Aleph-level ulpan once you have a handle on the ABCs.

Since the pandemic, Zoom-ulpan has become a thing, and can be a deep well of learning...

I'm planning to be more or lest constantly enrolled in Zoom ulpan for the next few years.  I prefer the less-intensive 2-day-a-week programs, and study through an organization called Ulpan Bayit.   This is a great way to meet people and really get better at Hebrew.

Consider hiring a traditional bnei-mitzvah style tutor to really go over things like the vowels, and to learn some of the liturgical context for Hebrew...

After I did early ulpan in Tel Aviv, I went back with a tutor and really locked down the Hebrew vowels and the pronunciation of the ABCs.  You could argue that this should have been the first step in my learning.  Hebrew doesn't use traditional vowels as in English, but uses a series of dots and dashes below the letters to indicate pronunciation.  While Israelis don't use the vowels after a certain elementary age, they are still useful in higher level ulpan when an instructor has to clarify how a word is produced.  I recommend Jewtor.

Read (and do exercises)!

There are good written resources for even elementary Hebrew.  I like the series "Hebrew from Scratch" and its workbooks, as well as the "Gesher" series of graded reading books.  Gesher starts at a level a little more advanced than Aleph-level ulpan, but it's still worth wrestling with as a pure-beginner.  The stores tend to be foundational to the modern state of Israel.

Go back into Duolingo and see how much progress you have made...

At this stage I started using Duolingo again and making really rapid progress based on all of the previous training.
