Is my filter "reasonable"?
I would say no. The time domain ringing time of your filter far exceeds the length of your signal, there isn't enough signal for the output to stabilize.
Can I do better?
Difficult to say. Filter design involves complicated tradeoffs between many different factors and the "best" really depends on the specific ...

Direct-Form II is the canonical structure to implement an LCCDE, using minimum number of delay elements and multiplications. The input $x[n]$ is placed on the left, and the output $y[n]$ is on the right, complying with the signal processing conventions.
DF-II structure, implements the poles (IIR part) before the zeros (FIR part), however this may be ...

If you talk about a moving average filter then you only have a single degree of freedom, namely the filter length (i.e., the number of taps). Consequently, given the number of taps, the magnitude of the frequency response is fixed and the cut-off frequency is given.
Note that you could also define the delay of the moving average filter as another degree of ...

I sadly don't have the reputation to comment on Fat32's answer, but let me try to answer directly instead: the frequency response of a digital filter is always relative to the processing sampling rate.
So if you design a filter with cutoff at 100Hz and 1kHz sampling rate, then you are really designing for a normalized cutoff frequency $f/f_s$ of 1/10 and ...
