If you don't want to root your phone, there are not many options left unfortunately. One idea is using FilterProxy only for 3G/LTE, since you have FoolDNS on WiFi. You have to add filters manually but as it accepts import/export with XML format, it's relatively easy. I do not recommend adding hundreds of domains as it will cause a lot of slowdown. Keep filters from about 50 to 100, though it depends.

Some notes for FP:

If you combine FP with FW, most traffic go through FP so it can somewhat decrease effectiveness of FW though you can limit FP by FW to some extent.
However of course, it's worth doing.

FP comes with some default rule sets but it's optimized to Japanese website so maybe most of them are useless for you.

As noted in Playstore, if FP is killed by Android you'll get into trouble.
Keep icon in tasktray, but if you don't want to see it you can safely hide it just as J_L did to LostNet.
However, even while FP is active, sometimes it causes trouble. First thing you can try is set FP status to BYPASS. Just tap green ACTIVE button in main screen.
Note BYPASS only apply to blocklist filtering, so redirect control and/or header modification are still active.
And some app just don't like any proxy thus cause problem.
I reccomend setting 2 access points up, like MyAP & MyAP2, with basically same settings except proxy one, thus you can quickly switch proxy on/off.

FP applies blocklist (or any other list) from upper side to lower until it finds match (or finds no match).
So performance wise, after you made your own block rules, browse website and use apps just as you always do, then hit counter in filter tab―Oh, dear, do your FP interface is optimized for English? Sorry I don't know but maybe not? It's sorry if Neutral Tao didn't made English version.
Anyway, you can see hit count just next to each rule, e.g.
[2] .google-analytics.com/ means FP cut 2 connection to that domain.
Then tap Android's setting button, then there're two options: Deny response & Sort.
tap Sort, and there're 4 options: matched number(ascending order) , matched number(descending) ,alphabetical (ascending) and alphabet(descending).
Tap matched number (ascending) so that the most hit domain comes top.
Then near the bottom, there should be not much used domain rule. if after days or weeks you found those rules rarely used you can simply tap the domain to disable it. Or if you want to delete it, just long tap it.
Note reboot your phone will reset those counter.

FP also let you to set redirect rule which helps e.g. remove annoying redirect some website use, or some redirect tracking (FP can't modify https connection so you can't remove redirect from Google's SSL search though FP can block https connection).

It's let you modify http header too, so e.g. you can remove Etag and/or referer, and/or modify UA and/or Accept-Encoding.
And you can set scope for each rule e.g. only for certain domain (www1.example.com), domain with wildcard (www?.*.com), or apply always.

Options for non-root adblocking? Other's include FoolDNS, specialized browser apps, Firefox Adblock Plus extension, etc.

Oh, don't forget Dr.Web though FW is paid feature.
BTW maybe you know, there was adblock in Playstore, but Google removed it.
But you can download them from...ah, sorry I forget the place where we can download non-store apps relatively safely, but some of you know?
I just have been forgotten them but remembered just now.

Also maybe we shouldn't use word 'ad block' too much?
Because maybe google find these word and consider, say, FilterProxy should be banned. lol

well, then configuring router firewall is also an option, though not flexible at all.
