Will the AVR-X1700H damage the RC80i?

No. The AVR-X1700H is rated for the RC80i's 8 Ω load as it comes.

What impedance setting should I use for the RC80i on the AVR-X1700H?

None: the RC80i is 8 Ω, and the AVR-X1700H needs no change for it.

Is the AVR-X1700H powerful enough for the RC80i?

More than you need. From a seat 2 m away, loud 95 dB movie peaks take about 13 W per speaker, and the AVR-X1700H is rated 80 W per channel. Cinema reference level, 105 dB peaks, takes about 127 W.
