I recommend waiting on Yoimiya, people are still in the "no, she's bad!" / "no, she's good!" argument phase.

Sayu is anemo and healer, so she covers venerer debuffing, element spreading and healing slots at once. Another benefit is her heals are very passive, you could drop her burst and just like Fischl it'll sit there throwing anemo explosions every second that can heal characters below 70% hp.
Her skill can be either a very fast kick (good for quick resistence shred), or you can hold it to roll across the field dealing anemo+absorption damage 2x every second, finishing it up with a anemo strong kick.
Her skill basically functions like ayaka/mona dash, except faster and easier to use, 10 sec duration, 11 sec cooldown.

IMO Sayu is worth getting coz she's super fun to play, but her damage output probably will only be good as sub-dps (like Fischl) or in large groups of enemies. Her healing isn't Qiqi tier at C1, but it's great that it happens on the side, immediately after you go below 70% if her burst is active. She'll heal the whole group based on your EM if she's on-field every 2sec with swirl.

Yoimiya seems to have good single target dps, which is also her weakness, in large groups she's bad.
