I like option 2 as long as the unsupported length does not get too long, as you say.  If the semi-rigid (blue tube), rather than flexible (red tube) Gold-N-Rod (or the Du-bro equivalent) is used, I am sure there is tolerance for a modest unsupported length.  We are talking about a 60 size plane here...

My goal though would be to trim the tube flush with the fuselage and have the plastic rod cut to a length that maybe sticks out of the fuse 1/4-1/2" or so.  The yellow rod is more noticeable against my planned white fuse than the metal pushrod that will be on the outside.  I was actually thinking that I could bury the plastic completely and let the metal rod go into the tube, but that may be a bit obsessive.

To me that looks and will function better.  As Mike said, the plastic would likely fail before the glue joint if the surfaces are properly prepared.  If you scuff up and then clean two surfaces with IPA before using CA, they can be VERY hard to get apart after a few hours of time.
