I'm doing Egyptian on my own using James Allen Middle Egyptian, which includes exercises. I combine it with Anki flashcards that I make on my own to have something to practice every day.
As for Latin and Greek, they're sufficiently different that you shouldn't be getting grammar confused. At least it hasn't been happening to me so far, and I've been learning both for a year now.

I found working through both at the same time to be helpful.
I used this to get started. If the interest continues i suggest for some self study.

Also the Egyptian Exploration society has some guided translations through zoom every few months.

You can easily do this yourself, Hieroglyphic is the easiest language to learn because you don't need to bother about conjugating verbs or remembering feminine and masculine nouns and you don't need to speak it (although we have a good grasp of pronounciation which I will come back to). Within one month you can understand almost everything you see (because mostly everything is repetition with the same phrasing and different names)
I recommend starting with Bob Brier's Decoding the Secrets of Egyptian Hieroglyphs which is a great introduction which you can easily do in the free month and it's also on Amazon. For fluency I recommend James P. Allen's Middle Egyptian 3rd Edition which also has 24 great lessons about Egyptian life and religion.
If you have some insight into Egyptian ortography you can now learn to speak it as the ancients did. James P. Allen's Ancient Egyptian Phonology has reconstructed earlier forms of the language with language internal clues, Akkadian cognates, transcriptions of Egyptian names in Cuneiform and the fact that Egyptian still lives on as Coptic in The Christian Ortodox Church in Egypt as a liturgical language. For example RꜤ-msj-sw mry-jmn anglicised as Ramses meryamun was preserved in Cuneiform as ri-a-ma-ší-ša+ma-a-i-a-ma-na allowing us to accurately reconstruct and read hieroglyphs:
𓁳𓄟𓋴𓇓 + 𓁩𓌸𓇌
RíꜤamasísa + mayamána
= "The sun is the one who birthed him + The one whom Amun wants".
Pronounced like so: Ree-Ꜥah-mah-SEE-sa + migh-ah-MAH-nah. Ꜥ is a glottal stop or a short brake like in uh-oh (uhꜤoh), capital letters are stressed.
I highly recommend Middle Egyptian by Allen. You can find it on Amazon or this thread has a link to the PDF. You could also look for Gardiner's grammar for supplemental instruction.
It takes a lot of practice to remember all of the hieroglyphs. If you have a Memrise account, I used this course to help me memorise the various literals. There are also several other courses on Memrise if you want to sort through them.
If you have Android there is a really good Dictionary app that uses Gardiner's list codes and includes transliterations.
Hope that helps. Good luck!
I'm self taught.
This book is a fantastic resource for teaching yourself.
