What is it about Virion that you like? Chrom's FeMU supports bring up her tactical abilities as well.
It’s nothing to do with her ‘tactical abilities’ the main story portrays the Avatars abilities as a tactician just fine. The point of Virion’s supports with the Avatar is
A. the pressure s/he feels because everyone is putting their lives in her hands.
B. Virion, someone who is shown in other supports (mainly Lissa’s) to be reluctant to trust people, he’s shown in his Lissa supports to be baffled at the amount of trust Lissa and Chrom show him, is willing to put his life in the Avatars hands. Virion trusts him/her and that for me means more than Chrom trusting the MU because as Lissa’s Virion supports again show, Chrom is a trusting person in general, it has less meaning in that case if Chrom is willing to trust a lot of people.
C. It is used to develop not only the fact the Avatar is a good tactician but that they seek to minimize casualties, Virion’s method might win the battle but at what cost? MU’s method saves lives.

More detail on the Avatars x Virion supports in the link above.
What does Chrom x FeMU give us? C support of her threatening him with a rock, 2 supports of them walking in on each other naked and your average, if a bit awkward, S Support
Chrom: Oh, er. I was hoping you could offer some advice on tomorrow’s route.Avatar: Fine. What are the options?Chrom: Well, according to this map, one route is this steep trail through the hills. Or we could circle the hills and follow the main road across the plain. I imagine either would work but wanted to see if you had a preference.Avatar: Hmm… I’d say the path through the hills. The main road would be easier, but we’d be more exposed if we encountered foes.Chrom: Right… That’s what I was thinking. Thanks for the advice. And, er… Yes! Well, that’s it, I guess! So…yes. Bye.
The part you mention is nothing special, all she does is pick between two options Chrom gives her. I’m sorry but that doesn’t measure up to her Virion supports in my eyes.
Chrom x FemRobin has it’s merits but I’m afraid your looking in the wrong places with this one.Â
