Please help - 1st upgrade questions

Hi all -
I'm going to do a budget upgrade to the stock system in my 2019 Prius LE. Maybe someday I'll be able to install all the cool stuff (amps, DSP, subs, etc.) but for now...
Thinking of working with Crutchfield because I know nothing about install and their system seems idiot-proof.
Planning to replace all the stock speakers & maybe the receiver.

Questions (all components are budget options recommended by Crutchfield)
1) - Would a Kenwood DMX4707S be an upgrade in terms of audio quality over the stock receiver?
2) - What about these speakers as replacements for the stock door ones: Focal ACX 165 2-ways?
3) - I'm thinking about adding Audiofrog GW25 2.5" mid/high's to replace the stock dash tweeters.

Your thoughts?
