Pretty sure I have 3 second power (maybe 5). I don’t really want anything longer than 5ish seconds when trying to see ‘what power am I doing now’. It does jump around a lot unless you are really keeping a steady effort.
For pacing longer efforts/climbs, I like to have:
3 second power
30 second power
lap power
This helps me see both the overall picture of where I am, but also the very recent past and my current power. I generally try to keep my 3/30 second power ‘on target’, while the lap average is more informational - I don’t adjust my effort based on that.
My Garmin is setup to display an unfiltered power value. To properly pace I want immidiate feedback if I overshoot my power target. If I had 3s average it would result in delayed feedback and a longer time until I would correct my output.
Power output is a bit jerky but that is just the way it is; filtering doesn’t change that, it just hides it. With practice it can be a lot less so, but immidiate feedback is key.
I use to use 3sec on my infrocrank’s (dual sided) - When I moved to L-only I felt the power fluctuated a little more so I moved it to 5sec. I much prefer 5 sec power (or longer) - it’s better to use RPE and check the power meter to make sure you’re on target rather than always trying to chase the perfect number

I’m not sure I would use just the current Zone since the zones can be quite large and for a given intended effort the top and bottom of a zone can be pretty different. For example, my Z2 is something like 170-235W. Riding at 175 and at 225 would both show the same on my computer but are two pretty different efforts.
Also, current lap power can be a bit of a trap. If I’m trying to do a 10min threshold interval at say 300W and after 6min my avg power is 295 and I then ride at 310 for the last 4 min to bring it up I just did a slightly different workout than I intended. I think it would be better to just try to keep it pinned at 300 the whole time and let the average be what it is.
I’m having a productive spring, and my FTP has risen by about 15% since the first of the year. I found that I was psyching myself out looking at power targets in watts because my old zones were stuck in my head. In other words, when it said “hold X watts for 10 minutes”, my first reaction was to think “I can’t hold VO2Max for that long!” instead of recognizing that X is my current FTP and I can, in fact, hold it for 10 minutes.
So I changed my power displays to percent of FTP, and now when I look down and see I’m putting out 102% of FTP, I don’t panic and think I’m going to blow up from doing VO2Max.
