Struggling With Indoor Flash-Lit Photography

I dread pulling out the flash when I'm indoors. Even when I bounce the flash off the ceiling, the resulting photos look artificial and for lack of a better word, weird. But often there's no practical alternative. I just have to keep practicing. During post-processing, I'm not sure how much I should brighten the photos. This is compounded by the fact that my photos don't look consistent across my home and work computers. Original: +1 stops of exposure in Lightroom: +2 stops of exposure in Lightroom: Which looks the best? If forced to, I'd choose the bottom one. Their faces are well-lit, but unfortunately the background is too bright. This can be mitigated by adjusting the fill light setting in Lightroom. But when I mix and match exposure and fill light settings in Lightroom, it gets even more confusing.
