Keep in mind that audio streaming, and playback of video, are completely different items.
A room which has a surround system in it with a TV, or a set of stereo speakers, with a TV, isn't going to be playing along as well as a room with just speakers in it. That's because a TV video source needs the audio to have proper lip-sync. This is not a feature that these audio-only devices usually keep in mind, and the end result is that the homeowner really pays the price.
Now, I haven't heard of Arylic before, but they seem like a perfectly acceptable, inexpensive option to something like Heos or Sonos, but you will definitely want to read reviews to see if they do the job.
A big question I would have for you is whether you intend to pull all your sources back to a central head-end location, like in your basement, or a closet, or somewhere else, or if you just plan to put these boxes in every single room uniquely.
I'm a big fan of bringing everything back to a single location.
From there, your speakers are all about your choice for each room and what is right. For rooms with a TV, a stereo set of in-wall speakers flanking the TV is nice, but angled in-ceiling speakers can work as well. In a better room, you may want better speakers to get that better audio. In reality, for background audio and a good upgrade over TV audio, I'm a fan of what the Monoprice speakers deliver. I lean towards their 8" 3-way in-wall speakers as a favorite:
In-wall speakers allow you to expand your listening environment throughout your entire home, as well as removing the clutter of giant box speakers, giving you back your living sp

For $100 a pair, they deliver better than average in-wall audio and are a significant upgrade over what is built into your typical TV.

Be aware that sound from in-wall/ceiling speakers travels both directions. So, any adjacent rooms to the speakers will get a fair bit of audio directed their way. Plan accordingly!
Planning carefully about what your goals are is always the best starting point. Asking questions and being ready with your budget to shift isn't a bad thing if you intend to stay in one place for years to come.
Be very specific about your audio and video goals as things really have changed in recent years due to networking.
Do NOT think about using wireless to the main devices. Use a wired connection for all of your Arylic (or whatever) products. Your wireless will be from your phone to your home network. From there, make sure you have hard line networking in place for the best results.
