I ended up deciding to stick with WP Show Posts and for now, to just manually specify the Post IDs via the shortcode, ie:
[wp_show_posts id="119" settings="post_id=186,328,222"]
I’m just wondering – do you have any opinion as to whether this approach would be better/worse from a performance standpoint, as opposed to the other approach of specifying the category and tag for each? I might have 10 of these lists on one page, so would love to do this in the most optimum way.
Also, is there any caching mechanism built in that can be leveraged or any advice you have there? We are expecting huge traffic spikes to this site, and these posts do not need to change often, so just looking to be as smart as we can when it comes to how we do this.
