On my 600D which does not have All-I compression bit rates increases are more critical.
The 70D ALL-I is just as good as max bit-rate enhancement, and supports ISO 1600, so its better than raw video for low light ~ IMHO.
I think the 70D is best used with ALL-I for video.
Raw video on 70D is frought with issues, 720p continuous or 1600/2:49 at 60s max. clip time,
but max ISO of 800 unless you want to worry about hot pixels or low light shadow noise.

My suggestions for focus peaks on, and zebras I would only worry about overexposure which 1% is pretty good.
If you shoot raw, and by that I mean timelapse or still pics then ETTR, which many recommend a 1/3rd of a stop.
RGB histo, I stopped using it as the peaks & zebras are all I need for clipping (perhaps on stills review or shot set-up).
On occasion magic zoom with 3X lossless zoom, but if you really want to get the best manual focus check,
I suggest LCD loupe with 3X magnification. Its more precise than focus boxes.
Especially good if you poke a whole in bottom of loupe and use touchscreen AF in video to pull focus.
Use the flash button to on/off aiservo and youve got a rather powerful video camera that pulls focus, follows focus, or fixes AF while shooting. ~ JMHO
