Mixed Voice Question

I am not sure about my voice type and since it is being developed it might shift in future. At this time I am likely a baritone type.

in usual chest voice B3 is where it tends to get a bit unstable and C# and above needs lot of pressure and volume to get clean tone out of it. 95% of the time it is hit and miss. Unstable notes. I never enjoy singing this range with chest pulling so I am trying to develop some sort of mix for this range.

Couple of questions:
1. Are there lessons/video discussion on light chest mix? will you please share anything relevant. I am looking for a little airy almost falsetto like sound, real soft but with some chest presence. The mixed voice lesson I have seen from Abram are still clean tones with solid cord closure. These are still hard for me and may be the lighter ones could rescue.

2. Imagine, I found that light chest mix and can develop singing B3 to A4 in that soft mix. To blend that tone with the rest of the lower register (lower than B3) do those notes also need to get a bit lighter or do you think I can still sing the lower range in normal open chest voice and just the higher register can apply that light mix?

1. The foundation for light mix is lots of head voice work! Please see below for some recommended courses on head voice and mix:

2. Depends on the song and desired style! In general, you might need to reduce volume of high chest to match a lighter mix. But I'd be wary to recommend pulling back in chest voice, if the overall goal is a strong, robust mix to match.
