I’ve been studying Japanese for over 15 years and I’ve come across a lot of study material. Maybe I can give you advice on what worked/works for me. But definitely check out many peoples advices, that’s what I did to optimize what works for me 
The most essential knowledge you’ll get from the Genki I/II books. Alternatively, you can use Minna no Nihongo, but I didn’t use that one. From what I hear they give you an equally as good introduction to Japanese, though.
On top of that, I recommend WK (which I only recently started, as you can tell by my level). I’ve done the RTK way before using Anki. If you don’t know what RTK is, it’s a book teaching you to remember ALL Joyo Kanji and you can, if you are very diligent, learn their meanings in as little as 30 days, using Anki for example as an SRS approach. Why I stopped used this system after reaching 1100 Kanji was because I decided I wanted to know the reading to and felt that learning compound works and vocab alongside studying the Kanji helped me retain them much better. One example now is 少年 (しょうねん). I could never retain the meaning of ‘boy’ because ‘a few’ nand ‘year’ in my head didn’t make it logic. But I knew, as probably everyone who knows even a tiny bit of Japanese, that shounen means boy. And since WK teaches you the Kanji reading and the meaning, I can finally remember this word. (I am sure that there will be many more to come for me). That being said, RTK was definitely worth if for me, as I am having a fairly easy start with WK with almost no problems on the Kanji meanings, and thus, as I can focus on the reading, also little reading problems so far.
To study grammar, I’ve recently started using Bunpro. I need to make up my mind about it, but to me, this is really the only available option for SRS (if you don’t want to use Anki). i’ve heard a lot of good things about it and currently I am using it alongside revising the Genki books with 1 chapter per day and doing the lessons on Bunpro, that you can sort by Genki order (or the order of other books!).
To cram vocab I am using Torii. Pretty self explanatory, workds like WK but with the japanese most common 10k words. it’s a good addition.
I also generally recommend Anki. There are tons of decks available online and I’ve only recently started making my own deck with vocab I come across while studying with books.
Now to books (aside from Genki + workbooks). I can recommend the books Nihongo soumatome and the accompanying small book (don’t know the name, but they have 4 weeks of quizzes, each day a specific amount of questions cover reading vocab and grammar). I also really like the TRY books. Additionally, I use the official JLPT books, old and new version to study for JLPT.
This sounds like a lot, and my study schedule takes around 3 hours a day in total. I do my revisions and (all available) lessons on WK, Torii (20 per day) and Bunpro (all the ones for the Genki chapter I’m studying). Then I usually work though one daily lesson of Nihongo soumatome and read a whole chapter of Genki (I have studied this previously already). Some days I don’t do either of the books, or do TRY instead or work on the Genki workbook.
I usually stick to the “recommended” WK schedule of 3x per day and additionally study the rest every evening after work.
Finally, welcome to Japan! I am also freshly living here and trying to fix to my lack of communication skills
